Sheets v0.1.0

Manage terminal themes, fonts, and opacity across Ghostty, Kitty, and Alacritty from one native macOS app.

Features

• Live theme picker with ~460 imported Ghostty built-in themes, plus your own, in one searchable dropdown, with a live syntax-highlighted preview
• Create a theme by hand (color wheel or hex, per palette slot), or edit whatever theme is currently applied — File > Create Theme / Edit Current Theme
• Import a sheets-theme.json via File > Import Theme… or macOS "Open With > Sheets"; export your own the same way
• Editing a pre-installed theme always saves as a new, separate theme — it can never overwrite the original
• Day / Night / Both theme designation, applied per app
• System-font picker (reads installed fonts via Core Text)
• Opacity slider with live percentage readout
• One-level undo for the last change made to any app's config
• Manually locate a config file if Sheets can't auto-detect one
• Help menu: check for updates, links to this repo and tylersuits.com, and a contact address

Supported terminals

• Ghostty
• Kitty
• Alacritty

Install

Download Sheets_0.1.0_aarch64.dmg below, open it, and drag Sheets into Applications. Apple Silicon (arm64) only for this release.

After applying a theme, font, or opacity change, quit and reopen the target terminal app to see it — most terminal config changes only take effect on next launch.

Known limitations

• No automatic day/night switching by system time yet — designation is manual
• Linux (Omarchy) support is code-complete (standard XDG config paths for all three apps) but not yet verified on a real machine
• Color picking uses the OS-native color panel, not a custom in-app wheel
