I love Yubnub, and recommend it to everyone, but the site gets slow or unresponsive at times. I'd pitch in a few bucks if a Firefox wizard wants to cook up a plugin that functions similarly to Yubnub but runs entirely locally, with customizable commands.

Yubnub is extra cool if you create a Firefox keyword search for Yubnub. Then you can go: "yb gi commodore 64" in the address bar and have it carry out the Yubnub command

You could do alot of the same stuff in Quicksilver. Maybe they just need to make it easier to add plugins to it.

Needs readline support! Really.
