I would like a possibility to Lock the UI only partially so you can maintain fx the top (tabbed menu) and your customized container to the right (vertical full stack) while still being able to add or remove tools to the area below Main 1+2 and to the right of the tabbed standardmenu in the top. Ideally every UI element should have a “pin this” in the top right, so the user can select which elements to “pin” or not.
