Answer 1

I don't seem to find that option directly through Git Cola.

Don't forget that, in command line, it is very easy to checkout by date:

git checkout master@{1 days ago} -- /path/to/file
git checkout master@{2013-02-13 01:00} -- /path/to/file

If you are talking just about the previous revision

git checkout HEAD^ -- /path/to/file

I should mention, as detailed in this blog post, that @{a date} refspec won't always work:

(won't always work) because it uses the reflog (which expires after some time).

The trick (as found on Nabble) is to lookup the revision on a certain date and check out that revision. This can be done in a single command:

git checkout `git rev-list -n 1 --before="2013-02-13 23:59" master` -- /path/to/file

Use the "View > DAG..." window to display all of the commits in the entire project. This window is referred to as the "DAG" window. You can also launch the DAG standalone by running "git dag" or "git cola dag".

From the DAG window you can right-click on any commit and "Reset" either your branch and/or worktree to any previous commit.

You can also use the "Grab File..." context menu action to grab an older version of any file, from any commit.
