Wherever I can see the envelope names, I'd like to be able to rename them so I don't have to constantly switch between screens. I always feel like I'm 10 clicks away from being able to do the thing I want to do.
On the /inbox/envelope-funding or /planning/budget, I'd like to be able to rename my envelopes with an ellipsis menu. Or move an envelope to a different group. Or delete an envelope.
