I am not really sure if things like this are already hosted in
translatewiki, but there are some very well known and awesome gadgets
(i.e., Hotcat and Twinkle etcetera) are in use in many Wikimedia projects
which could definitely use a valuable localization service.
Wondering if translatewiki can do anything about it at this point.
