[Feature Request] Workspaces available

[ri-zhan]

Description

Taking inspiration from Sideberry extension on Firefox or the Arc browser, being able to switch between multiple workspaces in the same window would be epic.

Expected behavior

[Describe what you expected to happen.]

1. At the top or bottom of the side panel, I click add Workspace.
2. Upon clicking add Workspace, I can name it and change the icon.
3. Click Done, and side panel brings me to new Workspace with a new tab open. Tabs from the other/original Workspace do not follow into this new Workspace. Does not open a new window.
