Hello,
I have a small question about KDE settings and can be set to Lancelot was cited as key windows in Unity Dash or Gnome Shell. I also question whether the software can be easily set penetration workspaces. The idea is that the application window protrudes over the edge is the second to the protruding portion.

can you explain your 2 question better? maybe provide diagrams and more detailed explanations of what you want and remember most people here do not know much about Unity or Gnome shell (Gnome 3?)

ps: using Goolge to translate your original question does not mean that their translation is easily understood

I apologize for my previous post. I hope that this post is more understood.

As to my first question. I know but knowledge of Gnome or Unity was unneeded. It was only additional information. It was just example that in Gnome and Unity, applet with applications is activating by pressing button Win. And I would like to make that Lancelot will be activate by pressing button Win.
As to second question. I mean that if someone window stick out beyond desktop to other desktop, it stick out part is visible on this second desktop. I try explain on picture.
