I run Linux Mint 15 with KDE 4+.

Consider this screenshot:

enter image description here

Underneath the LM logo, or beside the Firefox icon, above "File" and "Edit", there's a little circular button with a dot in the middle. I don't know what it does, and haven't been able to figure it out yet. Can anyone tell me what it does?

That dot is to stick window visible on all workspaces.
