Editor: how to show file tabs above / below the file windows?

[J.]

All of a sudden, the editor tabs of open files have changed their position: Now they are below the file frames. How can they be moved up again?

I am not sure if I hit some special hot key or did anything weird. I was wading through the editor configs, but nothing was really jumping on me.

Any help appreciated!
Using nightly build svn11499 (Sep 2018) on Win10.

Right click on a Tab and select "Tabs at top" in the Context Menu ;D

Side question: Why have the Tabs at bottom AUI design while when at top Native design?
