Quick little nitpick: opening a tab group tries to load every single tab simultaneously which for larger groups can lead to heaps of lag and ram usage. older tab groups only held onto the tab page and a thumbnail and loaded them when they were selected which was much better for me. Also the tab management page could be smoother. Lastly, I like how current pages can be retrieved when opening a tab group without saving to one before hand so I don't lose pages I didn't want to but I would like active windows to be saved to a new tab group automatically when switching to another group and not already a part of one but not with only "new tab" active.
