Livejournal commands would be sweet

I just installed Ubiquity and I LOVE it but my first thought was, I hope this has commands for Livejournal! To my disappointment it seems it does not. Not being so good with the internet language and the Javascript I despair at being able to write such commands myself, BUT if someone who does would like to make this LJ user and many others very, very happy, I think adding LJ commands to the collection would draw hundreds of LJ users to this application.

As I said, I know nothing about programming, so I don't know what can and can't be done with Ubiquity in this context, but commands I would love to see would allow me to:

* Preview my friends list the way that Ubiquity can preview google searches - even better if I can specify friend groups like the drop-down menu lets you on the top of the page, but it would also be amazing if you could tell ubiquity to look for certain items on the list, for example: lj friend find [any entry on the friend page containing this term].
* Preview userpages by typing the user name (so the command would be lj user [username] or something)
* Reply to an entry with a different account than the one I'm currently signed in with, without having to log out and in again, and then again afterward
* Quick commands for adding userpics

Obviously this is a sort of ultimate dream app here. I would be ecstatic about any good LJ commands, if anyone who knows how to do this sort of thing has some spare time and energy to create some. They would be vastly appreciated by me and many, many LJ users worldwide.
