Thanks for the kickstart. One thing, though: If there actually isn't a canonical location for this, wouldn't it make more sense to insert before editpage-copywarn? That would put it structurally slightly closer. (I haven't tried it yet, though; I wonder if we can insert before next sibling of wpTextbox1.)
MediaWiki:Edittools, while nice for things you might need only occasionally, is indeed at the bottom. For the characters missing from a non-frisian keyboard it would be nice to have a location somewhat closer. Aliter 18 jun 2009, 20.12 (CEST)
