Feature Request - Workspaces

[matheusmota]

Hi there.
Thanks for the great job with this extension.
I've been using Jupyter Lab Workspaces to manage/switch between projects and it works perfectly. However, there is no visual nor fast way to see/switch/rename/delete/clone workspaces.

I would like to humbly suggest a "workspace management" feature to the status bar, as it is very handy and is always on the screen.

Thanks
