I was discussing the possible implementation of Gadgets on LyricWikia with User:OneTwoThreeFall, and apparently Wikia are planning on discontinuing Gadgets and not replacing them with anything, just recommending use of Common.js etc. I figure it shouldn't be too hard to write our own replacement, since that's a significant loss of functionality.
We can utilize MediaWiki:Custom-* messages according to the MW whitelist, and I'm thinking of creating something on Special:BlankPage that mimics the current checkbox system (using the same index, description, and code page scheme as Gadgets for easier transition), except instead of a save button there will be a button to generate an importArticles statement to paste in the user's wikia.js.
Thoughts?
