Hi @wilkmaciej,

Thanks for making these changes that I requested, great work!

I’ll make some minor adjustments this afternoon, and then merge this feature request and include it in the next beta release.

Thanks again, I really appreciate your work!

Hi @wilkmaciej,

I really appreciate that you've taken the time and effort to contribute to Git Graph, and been able to implement new functionality that will be used by many users.

I've made some changes, and merged this feature request. As I didn't perform the merge through the automated GitHub PR process, I'll close this PR (even though it was merged in 1dffc27).

I've included an acknowledgement of your contribution in the Change Log included in the packaged beta release (and the full release once it is available), and in the GitHub release notes. Please let me know if you'd like me to use an alternative name, or link to another profile (currently it links to your GitHub profile).

If you'd like to use it before the next release, you can download v1.28.0-beta.1, and install it following the instructions provided here.
