How is this still a problem? Every dev who uses UE must run into this issue, including the people at Epic…? So, what, they’re all happy with their editor being jumbled up every time they start it? Not worth the 5 minutes it would probably take to fix it, literally persisting the order of a few tabs?
There is an excellent plugin I use called Asset Tab Manager, but that unfortunately does not handle all tabs such as content browser, log messages, and level.
