Themes & Customisation

🎨 The 23 Built-in Themes

Defined in BuiltInThemes.kt:

• System (3): System Default, System Dark, System Light
• Classic (12): Dracula, Solarized Dark, Solarized Light, Nord, One Dark, Monokai, Gruvbox Dark, Gruvbox Light, Tomorrow Night, GitHub Light, Atom One Dark, Material Dark
• Modern (8): Tokyo Night, Tokyo Night Light, Catppuccin, Rosé Pine, Everforest, Kanagawa, Night Owl, Cobalt2

All themes ship with a 16-color palette (8 normal + 8 bright), foreground, background, cursor, and selection colors. WCAG-AA contrast checks pass on all dark themes.

✏️ GUI Theme Editor (Wave 2.4)

ThemeEditorActivity — make your own themes without writing JSON.

• Color picker for each of the 16 ANSI colors plus FG / BG / cursor / selection
• Live preview pane shows your colors against typical terminal output
• Name and save — appears alongside the built-ins
• Duplicate a built-in theme to use as a starting point
• Optionally export the theme as JSON for sharing

📦 JSON Import / Export

• Import: menu → Import Theme → pick a .json file. TabSSH validates it (structure + color format) and adds it to your theme list.
• Export: long-press a theme → Export. Choose where to save via SAF.
• Compatible with the format used by other terminal emulators that ship JSON theme bundles.
• Shared with desktop: the JSON theme format is identical across mobile and desktop — when desktop ships theme support, your custom themes will move across without conversion.

🌗 App Theme (Light / Dark / System)

• Settings → General → App theme: Dark, Light, or Follow system.
• Live switching — no restart required (uses AppCompatDelegate.setDefaultNightMode).
• Material Design 3 with proper DayNight colors (values-night/colors.xml).
• This is the app chrome (toolbars, list backgrounds, menus). The terminal theme is independent.

🎯 Per-Host Theme Override

• From a connection's edit screen, pick a specific terminal theme. Overrides the global default.
• Useful for visually distinguishing prod / staging / lab — set "Tokyo Night" for prod, "Solarized Light" for lab, etc.

🏷️ Color Tags Per Host (Wave 3.1)

A separate, lighter-weight visual cue than picking a whole theme.

• Each connection profile has a color_tag field — an ARGB int.
• Pick from a palette in the connection edit screen.
• Surfaces in the connection list and tab strip — instantly tells you which host you're on.
• Independent from group color (which colors a whole folder of hosts).

⌨️ Customisable On-Screen Keyboard

• 1 to 5 extra keyboard rows above the standard Android IME.
• Pick which keys go on which row in Settings → Keyboard customisation.
• Modifier keys (Ctrl, Alt, Esc) can be sticky or one-shot.
• Useful presets for tmux, screen, vim, emacs.
