I suggest name of current palette be shown in title bar, it may be out of sight in the list.

Provide a Shortcut for the plugin (for completeness sake), no default - and no need for more than that. Keyboard warriors like me can Tab through the buttons

Below are some suggestions for the opening post.

Features
Adds a toolbar icon to access the palette manager.

Automatically detects .calibre-palette files stored in Calibre’s configuration directory.

Lets you select and apply a palette from a popup window.

Applies colors using Qt’s QPalette system.

Supports importing and exporting palettes for easy sharing.

Optionally auto‑applies the last used palette at startup.

Where is this option? Seems to always apply last used - which is fine by me.

Can be extended with .qss style sheets for additional UI tweaks (e.g., scrollbars).

Do you have a link to any For Dummies doco for this.


File Structure

Linux: ~/.config/calibre/palettes

Not necessarily - the CALIBRE_CONFIG_DIRECTORY EnvVar can change it, and configuration settings are in the Calibre Settings folder for Windows Portable installs

Best leave it out.

Combined palette files can include both light and dark specifications.

Optional .qss style sheets can be placed in the plugin’s resources/ folder (e.g., scrollbar-dark.qss, scrollbar-light.qss).
