Just wanted to mention, I've added some new options to wiktionary lookup gadget. One of them is to display it as a bar at the bottom instead of as a tooltip. (This idea comes from [[:fr:wikt:Utilisateur:Darkdadaah]] who made a gadget on the french wiktionary to display definitions on a bar at the bottom.)
Here's what it looks like so far. Its the wiktionary logo (or at least in some languages anyways) in the background.
