v14.20 [Solved] : How to hide tabs?

[Sander Bouwhuis]

I upgraded from v14.10 to v14.20 and now I see tabs above my file list where I didn't used to have them

I checked the View settings and Configuration menu, but don't know how to hide them.
Could someone please tell how to restore the hidden tabs like you could do in v14.10?

Oops! Found it!
It's in the 'Windows' menu.
