@George - Lots of great comments and insights on both sides here. I’m extremely glad to hear that the tree view isn’t going anywhere!
I for one, and it seems many others, would be doing a happy dance marathon were split tabs introduced. It seems like a fairly easy thing to add which would significantly improve the user experience. Just my 2C. (if you could also remove the minimum width from the left hand panel so it doesn’t have to take up so much space on my wide monitor that would be sweet too. )
Also just want to say that I’ve always appreciated that you and the team are on here listening to us and engaging in these conversations even when they might be difficult.
