just to let you know, WYSIFTW  has been augmented to offer
"one-click references". Only because someone recently said that
Wikipedia is too hard to edit... ;-)
To insert a reference at the cursor position in edit mode, click a
button in the sidebar, enter an ID (PubMed, ISBN, etc.), and the
appropriate "populated" template inside <ref> tags will be inserted.
This uses [[User:Diberri]]s template filling tool  via toolserver
(because Dave's tool does not generate JSON/callback directly).
No screenshot, as there is not much to see. Click button, select type,
enter ID, press return or OK, done.
The function also supports URLs and "free text".
