Perfect, just what I needed! I like how it can be controlled via the keyboard in addition to mouse. It just needs some kind of session management to avoid losing windows (it happened to me after closing and reopening firefox) and maybe storing windows to the cloud and be able to open just one window on another device.
I suggest using a dedicated session management extension. I haven't made any plans to add such a feature in Winger but I will explore whether it's worth it.
Storing windows and opening them on another device is possible with the Stash/Unstash commands and synced bookmarks!
