The best part of git log is git reflog. It's like suddently having eyes to see.
Just click the Recyclable Commits checkbox, and all the commits from the reflog are shown in the normal SmartGit log, integrated into the view just like every other commit, with all of SmartGit's usual tools available.
Want to see which files changed in a particular commit? Click the commit.
Want to see the diff for one of those files? Click the file.
It's all right there. No copying commit hashes or having to use any other commands to see what changed.
Stashes are treated the same way. Click the Stashes checkbox and they are also displayed as part of the normal log with all tools available.
I really like the way SmartGit integrates these separate Git features into a single unified log view.
