I don't think this is a good candidate for a library. Libraries should be code that is likely to be used by many addons. How many addons that need icon choosers is a user likely to be running at the same time? One, maybe two? Babble-Herbs and its ilk were deprecated for exactly this reason.
Also, wrong forum. This forum is for threads about libraries that exist, not for threads asking if a library exists.
Eh, if you can't handle being told you've made a simple mistake when there are forum descriptions and sticky threads explaining each forum's purpose, maybe Internet forums just aren't your thing. Would you have preferred your thread just be moved with no explanation?
He wanted to know if anyone was working on a library to provide an icon chooser, because apparently all of the addons that have icon choosers are too "integrated" for him to figure out how the icon chooser code worked. ???
BTW, is there any addon that replaces the default icon chooser ? Even if it is not really needed for macros because of "#showtooltip", it will become valuable with the new gear manager, that uses the same icon chooser.
