Spring RTS Engine

Where can I find more lua widgets than the ones that are embedded in the mods?
I often heard about some adv widgets (like, the one which permit to automatize airlift from a factory to a lift area) but donno where to find them.
(omg playing spring for ages and asking this only now <= nub)

edit : omg I just see that there is a lua script forum

You can also have a look at:

And I think an even more complete DB you can find in the SpringDownloader (should be laying around in your spring directory). Activate the module "Widgets" in it.
