Listing of known bugs

From time to time, one of my users discovers something is not working as it should. I immediately go into troubleshooting mode: try to replicate it myself, reading the help documentation, scouring the online posts, trying things out, etc. Then, I run into a posting that says it's a known bug. I know that addressing the particular bug needs to be weighed against other priorities, so at that moment, I'm content knowing that it's nothing that I do to fix myself.

However, in hindsight, I could have saved myself a lot of time (and cost) had I know it was a bug all along.  It would be helpful to have a listing of known bugs. I think it would save everyone a lot of time. If anything, it can a be skimmed down version of the master list.
