show diffstat summaries in changelog file headers
It is currently not possible to see a high level change count of a revision in the HgDevelopment log window. This would be useful.
A change count column would contain one to three numbers: the number of modified files, the number of added files and the number of removed files.
I could imagine it reading something like "(120) +10 -4" in the case of 120 modified files, 10 new files and 4 files removed.
