I've been using this theme and I really like it. One of my would-be favorite functions of this theme would be the buttons on the bottom taskbar to open up apps etc, but I don't know how to add anything to them to make them functional! How does one add applications to the buttons?

I'd love to know as well :-D
I can't seem to get it to work . . .
(sorry to be such a noob)
Thanks

With litestep it has a variable's system.

Meaning you set your favorites apps and it uses those for links thru-out litestep.
Well if the themer did it that way.

Go in to your Litestep Dir
then Utilities and look for EvarConfig.exe

Setup your paths to the common apps your use.
Then Litestep needs to be recycled to get that info loaded.
