Recently we have deployed an updated version of the error reporting server at [0]. I fixed the previous comments, added syntax highlighting to the stacktraces. I also added pie charts for visualization and added a new html view for incidents. I also now try my best to show only different stacktraces.
I would like your input on this version since this is as close to a final version as could be. The database has been seeded with a few reports that are fake but the last one is actually real to give you some feel about how a real report looks like.
I am not exactly the best designer out there, but I did my best. If anyone has any new ideas for improvement that would be great.
