I was just looking at the project tools and noticed that there isn't a bug numbering system in place. It is difficult, at best, to refer to issues by lengthy and/or random titles - needs some kind of bug/issue auto-numbering and search by number for more clear and historical tracking.
Also, do you have any plans to integrate any Gantt and/or report graphing features?
For the PT, other than integration as a vBulletin functional template, which has some obvious convenience benefit, I'm not sure of the advantages over more fully functional bug-tracking tools. How does the vBulletin team approach this trade-off internally, and is there a move to extend the PT for enhanced quality tracking?
