Are you talking about "widgets" or "plug-ins" ?
If you're talking about widgets indeed, then, apart from the one I made a month ago, and some other widgets someone else had made 5 years ago or so (sorry I can't remember who), there's nothing else. Just the ones you get with LCDstudio.
If you want plug-ins, then there's a sticky list on top of this room.
In either case, everything is right here, in this room. If you don't see it here, chances are, it doesn't exist.
Live long and prosper...
