+battery: use the same technique as in vpn_ip to avoid reset=2.
+
+---
+
+implement fake gitstatus api on top of vcs_info (or plain git?) + worker and use it if there is no
+gitstatus.
+
+---
+
+- call vcs_info on worker. the tricky question is what to display while "loading".
+
+---
+
+- add _SHOW_SYSTEM to all *env segments.
+
+---
+
+- support states in SHOW_ON_COMMAND: POWERLEVEL9K_SEGMENT_STATE_SHOW_ON_COMMAND='...'
+
+---
+
+add POWERLEVEL9K_${SEGMENT}_${STATE}_SHOW_IN_DIR='pwd_pattern'; implement the same way as
+SHOW_ON_UPGLOB. how should it interact with POWERLEVEL9K_${SEGMENT}_DISABLED_DIR_PATTERN?
+
+---
+
+add `p10k upglob`; returns 0 on match and sets REPLY to the directory where match was found.
+
+---
+
+when directory cannot be shortened any further, start chopping off segments from the left and
+replacing the chopped off part with `…`. e.g., `…/x/anchor/y/anchor`. the shortest dir
+representation is thus `…/last` or `…/last` depending on whether the last segment is an anchor.
+the replacement parameter's value is `…/` (with a slash) to allow for `x/anchor/y/anchor`.

+- add to faq: how do i display an environment variable in prompt? link it from "extensible"
+
+---
+
+- add to faq: how do i display an icon in prompt? link it from "extensible"
+
+---
+
+- add root_indicator to config templates
+
+---
+
+- test chruby and add it to config templates
+
+---
+
+- add ssh to config templates
+
+---
+
+- add swift version to config templates; see if there is a good pattern for PROJECT_ONLY
+
+---
+
+- add swiftenv
+
+---
+
+- add faq: how to customize directory shortening? mention POWERLEVEL9K_DIR_TRUNCATE_BEFORE_MARKER,
+POWERLEVEL9K_DIR_MAX_LENGTH and co., and truncate_to_last.

+
+fix a bug in zsh: https://github.com/romkatv/powerlevel10k/issues/502. to reproduce:
+
+```zsh
+emulate zsh -o prompt_percent -c 'print -P "%F{#ff0000}red%F{green}%B bold green"'
+```
+
+---
+
+bug: open a new tab and hit ctrl-p. an empty line will appear before prompt.
+
+---
+
+take a look at https://github.com/skywind3000/z.lua. it claims to have fzf support. would be nice
+if alt-down showed two groups -- one for subdirs and another for directory history (sorted by
+frequency of use? by last use? three sections? more key bindings?).
+
+---
+
+add `p10k explain` that prints something like this:
+
+```text
+segment     icons meaning
+
+---
+
+---
+
+---
+
+---
+
+---
+
+---
+
+---
+
+---
+--
+status      ✔  ✘  exit code of the last command
+```
+
+implement it the hard way: for every enabled segment go over all its {state,icon} pairs, resolve
+the icon (if not absolute), apply VISUAL_IDENTIFIER_EXPANSION, remove leading and trailing
+whitespace and print without formatting (sort of like `print -P | cat`); print segment names in
+green and icons in bold; battery can have an unlimited number of icons, so `...` would be needed
+(based on total length of concatenated icons rather than the number of icons); user-defined
+segments would have "unknown" icons by default (yellow and not bold); can allow them to
+participate by defining `explainprompt_foo` that populates array `reply` with strings like this:
+'-s STATE -i LOCK_ICON +r'; the first element must be segment description.
+
+---
+
+add `docker_context` prompt segment; similar to `kubecontext`; the data should come from
+`currentContext` field in `~/.docker/config.json` (according to
+https://github.com/starship/starship/issues/995); there is also `DOCKER_CONTEXT`; more info:
+https://docs.docker.com/engine/reference/commandline/context_use; also
+https://github.com/starship/starship/pull/996.
+
+---
+
+support `env`, `ionice` and `strace` precommands in `parser.zsh`.
+
+---
+
+Add ruler to configuration wizard. Options: `─`, `·`, `╌`, `┄`, `▁`, `═`.
+
+---
+
+Add frame styles to the wizard.
+
+```text
+╭─
+╰─
+
+┌─
+└─
+
+┏━
+┗━
+
+╔═
+╚═
+
+▛▀
+▙▄
+```
+
+Prompt connection should have matching options.
+
+---
+
+Add `POWERLEVEL9K_{LEFT,RIGHT}_SEGMENT_MIRROR_SEPARATOR`. If set, left segments get separated with
+`POWERLEVEL9K_LEFT_SEGMENT_SEPARATOR` followed by `POWERLEVEL9K_LEFT_SEGMENT_MIRROR_SEPARATOR`.
+Each is drawn without background. The first with the foreground of left segment, the second with
+the background of right segment. To insert space in between, embed it in one of these parameters.
+`POWERLEVEL9K_{LEFT,RIGHT}_SUBSEGMENT_SEPARATOR` is unused.
+
+---
+
+Add *Segment Connection* screen to configuration wizard with options *Fused*, *Touching* and
+*Disjoint*. The last two differ by the absence/presence of space between `SEGMENT_SEPARATOR` and
+`SEGMENT_MIRROR_SEPARATOR`.
+
+*Fused* requires line separator (there is already a screen for it) but the other two options require
+two filled separators similar to heads and tail. Figure out how to present this choice.
+
+---
+
+Get rid of `saved_columns` in the wizard and always present all options as if horizontal space was
+unlimited. `print_prompt` should print something like this if prompt is too wide:
+
+  Terminal window too narrow to display prompt.
+  Make it wider and press ENTER to refresh.
+
+Terminal dimensions will need to be checked more often.
+
+Try getting rid of the "press ENTER" requirement by trapping `SIGWINCH`. Might need to run `read -k`
+with timeout in a loop.
+
+Print all text with a helper function that keeps track of the number of lines remaining on screen.
+`print_prompt` will then be able to show a similar message for Terminal window being too short. This
+makes sense only for two-line prompts. This is probably OK.
+
+If `print_prompt` can be told in advance how many prompts we are going to display, it might be able
+to insert or avoid inserting `\n` in between, depending on terminal height. There is one screen
+where one prompt is a one-liner while another is a two-liner. This is fine because there are only
+two options. `print_prompt` can assume that all options will use the current prompt height.
+
+Don't use `print_prompt` directly. Create `ask_prompt` and use it like this:
+
+```zsh
+ask_prompt \
+  1 "No frame"   "left_frame=0 right_frame=0" \
+  2 "Left frame" "left_frame=1 right_frame=0" \
+  ...
+```
+
+There are two prompt questions that don't fit this pattern: `ask_empty_line` and
+`ask_transient_prompt`. The first is easy to adapt (`print_prompt` can print prompt twice if
+`empty_line=1`) but the second will probably have to be hand-coded.
+
+---
+
+Optimize auto-wizard check.
+
+```text
+time ( repeat 1000 [[ -z "${parameters[(I)POWERLEVEL9K_*~(POWERLEVEL9K_MODE|POWERLEVEL9K_CONFIG_FILE)]}" ]] )
+user=0.21s system=0.05s cpu=99% total=0.264
+
+time ( repeat 1000 [[ -z "${parameters[(I)POWERLEVEL9K_*]}" ]] )
+user=0.17s system=0.00s cpu=99% total=0.175
+```
+
+---
+
+Add the equivalent of `P9K_PYTHON_VERSION` to all `*env` segments where it makes sense.
