I'm adready working on those features for Lume:

- Think about widgetizing / feature toggling other stuff. Allow user to enable different functionality such as galleries, pinstr boards, music lists, lists in general.

- Implement multi-account switching. Keep this a free function. Make it easy to switch with a few clicks without going into settings. This will help with seeding new content.

And this feature really interesting, I will find out which is best UX for it:

- Implement list browsing. Make its easier to discover stuff by following lists of npubs.
