Today I went back to a project that I really like, Ubiquity for Opera. Usually I do that when I'm annoyed by something (in this case I needed to quickly convert currency amounts), or when I find something funny.
This time, Ubiquity gets some more commands and some updates to existing ones.
isdowncommand, that checks if a host is up, has been changed to be interactive. This is the first one that I managed to make interactive, as it requires a bit more magic than just opening a browser window.
