Yakuake can open unexpectedly when dragging a window to the top screen edge to maximize it. It would be better if Yakuake could identify if any mouse buttons were held down when the screen edge was touched and if so, not open Yakuake and ignore any screen edge triggering until the mouse is moved away from the screen edge.
I totally agree. Currently it's impossible to maximize a window by dragging it to top of the screen without open yakuake.
