Hey there!
I’ve created a free plugin that aims to improve editor navigation.
In Major Tabs: Level Editor, Blueprint Assets, Preferences, etc.
In Minor Tabs: Outliner, Content Browser, Event Graph, Construction Script, etc.
It will let you move between tabs using Ctrl + 0-9, Ctrl + [ or ] for the next and previous tab, and more!
You can check it out here:
Hope it helps! <3
