While working on the MKS VcsSupport plugin, I came across a few issues/complaints I would like to see addressed in future releases of TeamCity.
Some vcs's support both per file commit messages, and changelist messages (mks is one of these). It would be nice to have a file commit message next to each file entry in the changelist.
Again, it would be nice to see a timestamp next to each file in a changelist. MKS changelists may span multiple commits, so the timestamp may differ on each file.
It would be nice to see the file revision information along with the commit message and timestamp mentioned above in the file list as well.
