Panel now selects from four width tiers based on $COLUMNS (with a 6-col buffer per side before stepping up): 52-wide (default), 70, 74, or 78. Each tier carries richer category descriptions sized to fit the layout. The box is horizontally centered on every draw via a left-padding prefix. Key reader switches from stty min 1 to min 0 / time 3, giving a 0.3 s poll interval so COLUMNS changes are detected without a keypress. The erase formula is now wrap-aware: prev_max_line_width / COLUMNS gives the wrap factor, ensuring old wider panels are fully cleared after narrowing. Idle timeout ticks that detect no resize are skipped entirely.

# SYNOPSIS
|
||
# config-toggle [-h | --help]
|
||
#
|
||
# DESCRIPTION
|
||
# Opens an interactive full-screen TUI for toggling 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
|
||
