Ledge

Ledge is a free, open-source MacBook app that puts the otherwise idle notch to work. It transforms the static notch into a status area, showing things like music playback, your next meeting, and more. The app is positioned as a way to make use of space that is usually unused while you work.

Ledge also keeps your agents working even when the lid is shut. Feedback is welcome through the project's website at ledgeapp.dev.
