WebIssues is a great application; I absolutely love the look and how it operates.
One thing I don't see at least at first glance, and I apologise if it is there, or has been suggested before, is tracking of time spent in activities related to the issue, ie a start and end time for each activity such as debugging, coding, documentation etc.
I'm not too concerned with having selectable activity types as I could type them in free-form; I'm primarily interested in capturing time spent.
Currently there is no such function. I'm planning to add more features related to project management, including time tracking, in one of the future versions.
