I love the different views for the bookmarks, but it will be even better if I could choose my prefered view across the app or a board. So every new bookmark will have the view I want in that context.
Since you can already set the view for every section, you could have a board with only bookmark panels, but one section with tiles, and another with compact bookmarks.
And for the Boards, I mainly use the Kaban view so I would like to have all my new Boards being Kaban, while still having the option to change the view later.
I also tried to show how the global setting could look like in the settings menu. Hope you like it.
