almost works for me but not quite :(

- no way i can see to include multiple windows in a group (for example, having multiple windows open for school and when i finish, unloading those tabs to open windows in a group for my art project. why does every window have to be a separate group?)
- difficult to add current tab/tabs/window to an existing group (a single and intuitive button for this is nice, like tab stash has)
- "other tabs" also not separated by windows, feels cluttered and confusing
