@sjouke-duinstra said in workspaces over multiple windows:

right now if you get a new window all the workspaces are empty

Yes. Each workspace gets its own set of tabs for each window. You can use this to your advantage if you want. For example, if you just give the workspaces numbers for names and generic icons., you can put what you want in them in each window. You just have to remember what number is for what in each window.
