Use compact tab mode
Enable following

Add sidebar button to tab bar
Restart Orion (you can skip this and result may differ🤦♂️)
Check 3-dot menu of each saved window
Open in Separate Window is available for the 1st window, but not the last one


Issues:
- I think in the current logic,
Open in Separate Window should be available for all window at all times?
- If there are 3 or more saved windows, and the active window is not the first one before restart, result of step 6 may varies. (I am too sleepy to find a pattern🤦♂️)
Suggestion:
a. Remove Open in Separate Window altogether. It is unnecessary. User can open a new window via menu or shortcut, then switch to the saved window they want.
b. open new window, when triggered from a saved window, instead of creating an new 1-tab saved window, should just open the active saved window in the new window. If user want a new saved window, they can use the + button. Right now we have to keep deleting/closing the new 1-tab window.
PS: Can we do something with the terms saved window? I think I lost too much brain cells after typing (b)😵💫
