I recently started using the Modific Sublime Text package. It highlights (with a subtle icon in the gutter) lines changed since your last commit. It supports Git, Subversion, Bazaar and Mercurial.
It also has some other useful features: view a file diff, preview committed code for the current line, revert a specific change, and cycle through changes.
By default, it uses the svn binary on PATH. For my Windows machine I configured it to use svn.exe out of my Cygwin install:
{
"vcs": [
["svn", "C:\\cygwin\\bin\\svn.exe"]
]
}
On my Mac, I had to set this option to true:
{
"svn_use_internal_diff": true
}
I’m finding it pretty useful.
