I was just on the website addon page.
Wanted to see if any other portals have been made available for Elk.
Typed "portal" in the search box at the top, hit enter
Got back nothing at all.
Acted like all it done was refresh a empty search box.
It's js-driven and you get the results directly while typing (actually it just filters a json file, there is no way to POST since it's 1) html based and 2) hosted at github). :)
ETA: actually, for the few that are tempted to push enter we could just capture it from javascript and stop the reload, while for those not using js.... that is a problem, but...
