Yes, let's hope the one-window -tiles will be possible in the future. REQ: multiple windows.

Some concerns of mine:

- new tiles always open with the tabs sidebar open
- "add tile" works only with a blank / new tab instead of existing
- simply clicking on and off and on again the icon of the add-on does open a layout consisting of blank tabs instead of the same layout and needs to "close layout"

request: when I have place for e.g. 3 tiles that act like groups with multiple tabs in them if would be an advance to be able to save the session including multiple tabs
