What I find especially powerful is when reviewing files in the commit window you can stage and commit subsection of files.

It allows you to really quickly separate out different change into unique commits and gets rid of the need to make messy I-did-A-and-then-did-B commits.

Select the lines you want in the commit window -> Right Click -> Stage Lines.

You can also revert selected lines, but for some reason it's grayed out half the time... I'm not sure what black magic controls that feature.

You can do all of that in the CLI but it's a lot more clunky and time consuming.
