Not a bug, apologies if this is not the right place for this but this is where I was directed. ("Report bugs and wishes at https://bugs.kde.org/") Yakuake opens from the top of the screen. With my preferred layout in Plasma, the top of the screen has a single panel and there is no panel at the bottom. It would be nice if I could open Yakuake from the bottom of the screen, and I can imagine opening from the left or right side would be nice for other set ups as well.
I don't know how I missed the other ticket, sorry. *** This bug has been marked as a duplicate of bug 150631 ***
