In the meantime, I'm going to toy with the idea of creating a wiki page dedicated to the "most annoying usability bugs" for Intrepid beta. Some of them may be small and squashable, others might remain open for months. That's fine.
Candidates for annoying bugs are anything that aggravates you about Ubuntu. Using the system should be fun, even if it's not very functional. Stuff like repetitive dialog boxes that ask the same question over and over (or worse, pop back up after you told them to go away) are perfect candidates for this list.
I encourage everyone to file more usability bugs. This is a good example:
As it is, the program is perfectly functional. Assuming, of course, you can intuit how to use it, and not get scared off (or perhaps print the whole document out of caution instead of just the possibly incorrect range). Fixing this sort of thing is just as important for many users as actual functionality.
