Hey! Us guys over at Templates Wikia really wish that we could make a URL like:
/wiki/Special:Export?link1=Template:Foo&link2=Template:Foo/doc&link3=Template:Foo/dependency
and have it fill out the text field from Special:Export with those three links.
We've discussed how it might be helpful for the problem of exporting templates with dependencies, yet excluding certain templates (like our custom Documentation template that the end user doesn't want. Alas, me and the other active contributor don't have the Javascript knowledge.
Would this be hard for someone to whip up?
