Organize itches into a folder hierarchy
Maybe having subfolders dedicated to developing test cases and patches will help.

+# Emacs
+
+- center/top point when
+ - moving to text/tag search hit
+ - going to man page section
+ - opening eww on an anchor
+ - visiting a function from its Help buffer
+- make font-lock stop background at fill-column or max(len(line) for
+ line in paragraph) rather than window-width when text spans >1 lines
+- shell-mode
+ - add faces instead of reusing font-lock-{comment,string}
+ - understand `autocd` and `cd !$`
+ - use Bash completions (e.g. `ls TAB` in a folder with one file)
+- [.dir-locals changed priorities][bug#30008] between subfolder and
+ major mode from 25 to 26
+- eshell: `ls --group-directories-first` does not color folders
+- emoji support
+- eww, gnus-article: adapt filling to window width changes
+- scroll-lock-mode
+ - cursor stuck on lines wrapped by visual-line-mode
+ - cursor stuck on lines with 😛
+ - scroll when going down newline with forward-…
+- matching-paren analysis fails: `;; (here is\n;; a comment)`
+- some modes redefine C-M-h, which makes this binding hard to
+ override; could mark-defun consult functions/values exposed by major
+ modes instead?
+- make ellipses for "invisible" text easily customizable (src/xdisp.c)
+- Man-mode: make isearch skip end-of-line hyphens
+- when opening `.gpg` files in a TTY, some characters (e.g. TAB) are
+ swallowed by Emacs instead of being forwarded to the gpg prompt;
+ these characters are then inserted in the decrypted file's buffer
+ (see `epa-file-insert-file-contents`)
+- let TRAMP fetch Google Drive credentials from .authinfo.gpg
+- icomplete's C-j does not choose the first completion as advertised
+ on empty input; it chooses ".", which AFAICT comes from the fact
+ that icomplete-exhibit calls completion-pcm--filename-try-filter
+ while icomplete-force-complete-and-exit simply calls
+ minibuffer-force-complete-and-exit
+ - likewise, if a folder contains foo.c and foo.o, "C-x C-f foo"
+ hides foo.o, yet C-j completes to foo.o
+- calendar uses default X resources when run in its own frame; see
+ `calendar-frame-parameters`, `x-handle-named-frame-geometry`,
+ `(make-frame '((name . "")))` vs `(make-frame '((title . "")))`
+- use compilation-mode-line-… faces for compilation-num-… indicators
+- "é" is not erased with a single DEL stroke, despite [Unicode
+ conventions]
+- sort tar archive members by name; serving suggestion:
+
+ ``` elisp
+ (defun my/tar-sort (info)
+ (sort info (lambda (a b) (string< (tar-header-name a) (tar-header-name b)))))
+ ;; Apply to tar-parse-info in tar-summarize-buffer.
+ ```
+
+- add a command or minor mode to highlight marks; serving suggestion:
+
+ ``` elisp
+ (save-excursion
+ (dolist (m mark-ring)
+ (goto-char (marker-position m))
+ (pulse-momentary-highlight-region (point) (point-at-eol))
+ (sit-for 0.1)))
+ ```
+
+- StackOverflow-like suggestions when reporting bugs
+- match data vs. `:eval` during redisplay: cf. [bug#31586]
+- make vc honour `.gitignore` so that `project-find-file` completion
+ is not cluttered with ignored files
+- in a folder with a .git folder and a .gitignore file,
+ - `C-x C-f .gi TAB` completes to .gitignore
+ - `C-x C-f .git TAB` says "not unique"
+- add some Custom machinery to save additions/removals to list
+ variables; as things stand, once I add/remove items and save the
+ variable, I miss out on changes to the variable's default value:
+ e.g. `git-commit-setup-hook` recently added `bug-reference-mode`,
+ but I never realized it because I customized the hook to add some
+ personal functions
+- e-pair-mode inserts a closing `$` after point in tex-mode, but
+ inserts a new pair instead of overwriting when pressing `$` again

+
+## Better out-of-the-box display for FORM FEED
+
+By default, FORM FEED is displayed as a dumb `^L` glyph. This is
+surprising considering it shows up in so many places: Emacs source
+files, help buffers (e.g. `describe-mode`)… You can even see it in
+source files of other GNU projects, like GCC.
+
+"Pages" are important enough to have their own navigation and
+narrowing commands, yet their default delimiter is displayed as an
+unassuming control character.
+
+I like the way form feeds are displayed with [`page-break-lines`];
+magit's `show-lines` blaming style achieves a similar look.
+
+Having this kind of display by default would make it more obvious that
+this character serves an actual purpose; as it stands, it looks no
+different from some stray CARRIAGE RETURN.
+
+This could be re-used by e.g.:
+
+- `describe-symbol`, which uses the following method to visually break
+ up multiple symbol definitions:
+
+ ``` lisp
+ (insert "\n\n"
+ (eval-when-compile
+ (propertize "\n" 'face '(:height 0.1 :inverse-video t)))
+ "\n")
+ ```
+
+- Custom buffers, where sections are delimited visually with a
+ 999-character wide underlined space.
+
+Full disclosure
+: This reflection started because moving over this underlined space
+ with `truncate-lines` on causes the screen to jump horizontally.
+ This specific problem should be fixable without dragging FORM FEED
+ display into the discussion, but I feel like the latter is the
+ more interesting issue ([who on Earth] enables `truncate-lines` by
+ default anyway).

+
+## Dired
+
+- allow "columns" to be toggled; more specifically, make it possible
+ to hide ownership, permissions, number of hard links…
+
+- make the filename stand out
+
+- `% r` does not support some `\` constructs (`\#`, `\,`)
+
+- add a face for broken symbolic links
+
+## ERC
+
+- move timestamp to a better position (see `stamp` module)
+- play well with whitespace-mode
+
+## Org
+
+- dissociate sub- and super-script fontification from everything else
+ in org-toggle-pretty-entities
+
+- org-clocktable trips on DST:
+
+ ``` org
+ #+BEGIN: clocktable :scope file :maxlevel 2 :step day :stepskip0 t :tstart "[2018-10-15]" :tend "[2018-11-15]"
+ #+END:
+
+ * foo
+ :LOGBOOK:
+ CLOCK: [2018-10-26 Fri 08:00]--[2018-10-26 Fri 17:00] => 9:00
+ :END:
+
+ * bar
+ :LOGBOOK:
+ CLOCK: [2018-10-29 Mon 08:00]--[2018-10-29 Mon 17:00] => 9:00
+ :END:
+ ```
+
+- make org-ctrl-c-ctrl-c call `(org-clock-update-mode-line t)` when
+ point is on the clocked-in heading
+
+- new command `org-clock-in-late` to clock out x minutes ago from
+ previous task, and clock in x ago on task at point
+
+## Language support
+
+- fix builtin/keyword distinction for Bash & Python3
+- highlight variables inside strings, eg
+ - `"a ${variable} inside a double-quoted string"` (Bash)
+ - `'a format string's {variable}` (Python)
+- do not highlight a single-quoted command substitution
+
+## read-passwd
+
+- prevent kills from ending up in the clipboard
+- add command to temporarily reveal password
+
+## whitespace-mode
+
+- skip line/wrap-prefix variables and properties
+
+- highlights the adaptive-wrap prefix, although weirdly enough the
+ whitespace *faces* are not applied
+
+- in org-indent-mode, adds a spurious (unfaced) space marker before
+ paragraphs; somehow transient-mark-mode knows not to highlight this
+ space, maybe the answer lies there
+
+## External libraries
+
+### adaptive-wrap
+
+- a commented-out line with no space between the comment delimiter and
+ its text will get padded with the comment delimiter:
+
+ ;(some very long line)
+ ;; ⇒ wrapped with adaptive-wrap-extra-indent set to 4:
+ ;(some very
+ ;;;;;long line)
+
+### magit
+
+- customize current-tag function so that one can add `--first-parent`
+- prevent section highlight overlay from hiding tag face background
+- when quitting ediff conflict resolution, the "save buffer" prompt is
+ out of focus, one must ALT-TAB out of the ediff control panel first
+ (noticed in Emacs 27; 25.1 works fine); possible culprits:
+ - magit
+ - ediff
+ - smerge
+ - yes-or-no-p
+ - read-answer
+- if deleting a remote branch fails (e.g. due to wrong credentials),
+ `update-ref -d` is still run
+- make status buffer understand and display `typechange` e.g. when
+ replacing a replacing a regular file with a symlink
+- when ignoring a file in a subdirectory, magit attempts to
+ `git add .gitignore` (i.e. toplevel `.gitignore`), which fails
+
+### markdown-mode
+
+- support [shortcut reference links]
+- move point past header after C-c C-t !/@
+- update sub-superscript regex to allow L~i+1~
+- make justification work with indented blockquotes
+- add "ini ↦ conf-mode" to markdown-code-lang-modes
+
+[shortcut reference links]: http://spec.commonmark.org/0.27/#shortcut-reference-link
+
+### rg-mode
+
+- make -project DTRT in dired
+
+### page-break-lines
+
+- borked in magit-diff
+
+### diff-hl
+
+- colored fringe line is discontinued on lines featuring faces with
+ heights greater than 1
+
+ ``` shell
