Pinned or Remain on top Menus.

i know many probably asked for this for ages, but now with 2.8x series i feel we could have this at least for the built-in menus, having to press hotkeys to invoke them each time is counter productive and slow ,each time i want to add a new object i have to press "shift+ A" and go to mesh menu when we could just invoke it once and have it with pin button enabled.......we already can tear-off editors and create a new window & i managed to keep them on top using an external program...but i can't do it for the internal menus which requires low level coding skills , so plz devs consider this for future blender version, thanks.
