In my work, I often use specific Groups like hm://...Cttho and hm://...oeMyG. If these Groups were more easily accessible with persistent navigation, including improved collapsing, expanding, and focused-level functionality, it would significantly enhance my workflow.
However, in the current implementation, only the account outline persists. Group outlines we all go away every time you open a new document. Hence, I have to Click favorites -> Search for the Group -> Expand and focus the hierarchy, -> Get to the point I was at before. These are a lot of clicks in the world we live in, of one-click away from what I want! :)
