Deskzilla is very cool.
We've enabled the Bugzilla time tracking feature but these fields do not appear to be available in Deskzilla.
What would be really cool is if Deskzilla could help with the time tracking. So in addition to being able to type in the fields directly, a bug could have a "start timer" and "stop timer" button. The idea being that you hit the "start timer" button when you start working on a bug, then hit "stop" when done. Deskzilla could then fill in the fields appropriately.
Asking too much? :-)
