It would be great if you can combine certain pages or folders with workspaces. So that when you go to a certain page the layout of the linked workspace is shown.
For instance the kanban page has no need for a left and/or right sidebar and should be as width as can be to facilitate more lists.
This could possibly be done by adding a tag exactly matching a certain workspace name like #workspace/default to link the default workspace to that page.
I have a “full_screen” workspace so the kanban page should get the #workspace/full_screen tag so it is presented at full width.
