It would be great if we were able to collapse the main sidebar. Manytimes I wish to hide it to make better use of precious screen space, & focus on the main area rather than the outline.
You can! Just click the same icon as the one that’s currently active in the sidebar → for your screenshot this would be the “Overview” (three horizontal lines).
The profile pic syncs with your Supernotes account, so just add a picture there and then log out and back into the Community forum. I hope that helps!
