vladstudio Thanks for sharing your ideas in such detail manner. I assume that tab kanban view would replace current "Tab View" in Orion (it also has to be reachable for people who do not use vertical tabs).
If so then it is exactly what we were thinking about. If there is only one group/window it would still look pretty much like it does now and the user shouldbe able to zoom into any tab group to get a similar view.
I researched this topic a lot in the past, and Firefox had this idea of Tab Candy which later became Panorama view extension. The spatial organization where the user has infinte canvas to organize their tabs + notes also made sense. Check my notes below in assorted/random order if you want to think more about this.
