It makes much more sense to display some advancements (in this case the vanilla "Adventure" tab) horizontally (picture 1) (with icons orientated correctly, of course) instead of vertically (picture 2).

My suggestion is: add a way to toggle between horizontal and vertical modes, as shown by pictures 1 and 2.

I checked the settings, but didn't find a way to do so.

yeah, duplicate of #4

I should really try to wrap my head around it.
