1 - Would love to see that if you have 4 tabs, and you decide you need a 5th, when you increase your tabs it does not rest all the tabs. I have many projects that have 10 tabs, I line them all up, then decide I need one more, and it resets every tab and I have to realign them. It would be great to just be able to keep existing ones where they are and just add a new one to move around.
2 - Would love to see a way to right click on an item and add a tab at that specific point without adjusting anything else.
