Improve multi-project selection

Problem to solve

It can be confusing to change the currently selected project. We document the process but the discoverability could be improved as it's not very clear how one can choose which project is currently selected.

Proposal

Improve Workflow view to surface button or collapsed state for additional remotes. See slack thread for further discussion

We probably should add a button to the line to make it more clear you can clear the selection, it's not obvious at all

Maybe in the tree view for a repository we can show a collapsed section for other remotes/projects. :thinking_face:
