Someone should make a gallery of gadgets, with a link to download it. Kinda like with extensions.
Topic on Extension talk:Gadgets
In addition to future plans for Gadgets 3.0. In the present there is:
- Special:Gadgets on mediawiki.org
- Special:Gadgets on en.wikipedia.org
- Special:Gadgets on meta.wikimedia.org
Each gadget has a description, links to source code pages, and an Export feature to download it as an XML bundle that can be imported using Special:Import on another wiki.
