- Add __fish_user_dots_path as 8th entry in vars list - Update panel_h from 14 to 16 (matches draw function's 16-line output) - Clamp cur_row down to min(7, ...) to allow navigation to path row - Add did_redraw flag (reset per iteration) to skip double-redraw after Enter - Add Enter handler for row 7: erases panel, prompts for path, sets or clears __fish_user_dots_path universally, redraws, sets did_redraw - Special-case RIGHT on row 7 as no-op (path is set via Enter only) - Special-case LEFT on row 7 to clear path var via apply DEFAULT - Add Enter key hint to --help navigation section - Fix EXAMPLE block in __config_settings_draw docstring to include 8th arg

# SYNOPSIS
|
||
# config-settings [-h | --help]
|
||
#
|
||
# DESCRIPTION
|
||
# Opens an interactive full-screen TUI for managing fish config settings,
|
||
# including the six opinionated component categories (C1–C6) and the master
|
||
# disable variable, without having to remember variable names. Two scope
|
||
# tabs allow independent per-scope configuration:
|
||
#
|
||
# Universal — persists across all sessions (set -U / set -Ue)
|
||
# Session — active for the current shell only (set -g / set -eg)
|
||
#
|
||
# Values are changed directionally with the arrow keys (or vim-style h/l)
|
||
# along an OFF ← DEFAULT → ON scale, and apply immediately — no confirm
|
||
# step. Always available regardless of __fish_config_opinionated state.
|
||
#
|
||
# ARGUMENTS
|
||
# -h, --help Print usage and exit
|
||
#
|
||
# RETURNS
|
||
# 0 Exited normally (q or Escape pressed)
|
||
# 1 Unknown flag passed
