As of SourceTree 1.9, there does not seem to be an easy way to commit a single file. In version 1.8 you could right click on a file and commit an individual file, but the feature is gone in 1.9.
The only way I can see to commit a single file out of a bunch of changes is to unselect all of the checkboxes, tick the checkbox next to the file I want to commit and then commit normally.
What happend to the right-click Commit option? I can Log, Blame and Reset an individual file via right click, but not Commit.
Thanks.
