I want to separate a tab from my main group, perhaps to work on two windows side by side.
When the new window spawns it also spawns all my pinned tabs to this isolated window
Duplication of pinned tabs for every isolated window is inefficient and uses up resources needlessly, in this scenario the user only wants the window isolated and not all the pinned tabs, since these remain in the orginal window
Having pinned tabs regenerate when all windows have been closed is great so to solve this I suggest the user is asked initially in the scenario outlined to “isolate pinned tabs too or just this tab? and secondly Remember this selection”
I would also argue that this should default behaviour and that the current behaviour is optional and controllable in the tab preferences area
