Yes, I think it has some use for game makers but not for players.At the moment this database is the only way of acquiring widgets enmasse outside of ripping them from games and spending hours trawling the lua forum.
But even in that case:
camera widget:
version on widgetDB: Entry-Date: 2010-09-07
http://widgets.springrts.de/springinfo/index.php#155
version in zero-K:
http://code.google.com/p/zero-k/source/ ... start=3382
has a dozen commits/changes/fixes made to it, more up to date.
Which one would you get?
Problem is that once things that are still wip are uploaded to multiple sites, some mirrors do not get updated. So is why I never used it either for up/download.
I do not know how that could be solved...
There are some interessting things on the widgetDB that afaik currently no game uses, ie the "dynamic blob shadows."
