Phone [Q] Launcher appgroup hide titel and fix position

i use standard Z2 launcher and gem xposed and many setting are very usefull.
but two things i can't change, may be it's not possible?

tap on a appgroup opens the window one row under the collapsed appgroup position
tap an appgroup in row 1 opens below in row 2
tap an appgroup in row 2 opens below in row 3 and so on
but it should open on a fixed row may be the first.

when i tap on a group i know what i do and see the apps in there.
so i don't need the big title row, this row should be smaller or hidden.

any suggestions, tricks or tools to change 1. and or 2.

Thanks in advance
