Hi, I am aware that cryptpad already has the options for a light/dark/system theme.
However, some browsers don't allow websites to access system settings for privacy reasons and so "system theme" doesn't work and so light/dark has to be selected manually. Because of this it would be nice to have a small icon at the top to click and cycle through the theme options. Ironically, this forum.cryptpad.org has this feature (at the top, left from the account dropdown), but cryptpad itself doesn't.
Suggestion: Add a button at the top to manually toggle light/dark theme.
