KSmoothDock 2.1nt patch. Added features:
-hand cursor (from mriya3)
-tooltips (from mriya3)
-configurable space between icons (it can cause "garbage" on the dock if too small)
-renamed menus and directories for better KDE compliance
You have to rename the ~/.ksmoothdock/menu directory to ~/.ksmoothdock/applnk and reconfigure ksmoothdock.
This patch will be sent to the original author, it will not be maintained as a separate fork.
