First, thank you for your time spent creating and improving Ubiquitous, I couldn't stream without it.
Please consider adding chat support for Azubu.tv. I think they use IRC (QuakeNet) under the covers.
Consider adding editable notes for people in the chat channel. I have a terrible memory, but I'd like to remember tidbits about my viewers (preferences, what country they're from, what they like to see, &tc.). It could just be a simple sqlite db with their username as the key. Right clicking or double clicking on a name in chat or in the viewer list would open up a simple text box to enter in information. Hovering over a user in chat/viewer list would display the the information you've entered previously as a tooltip. If no information has been entered, no tooltip appears.
I could of course use a separate "customer management" program, but I feel that "user notes" would be a great, simple-to-use addition to Ubiquitous, assuming it's not too difficult to implement.
