The look of ungit would confuse my users I'm afraid.
In the end I whipped up our own solution, with the added benefit of it being more efficient to the problem domain.
Take a look at https://files.ahall.se/n8n-gitted.mp4 where I demonstrate the functionality. The user makes changes to the n8n workflows, goes to the git system page and syncs the workflows to the git repo residing on the same docker as the n8n instance. User can then choose workflows with changes that are to be commited, types a message and is done.
Selecting an earlier commit does a git checkout on that commit and shows the files. Clicking on a file copies the contents of it. In this case, the workflow can be pasted into n8n and the user can pick and choose what was desired to bring back.
The git system page is static HTML and javascript, and communicates through webhooks to a git workflow in n8n. https://files.ahall.se/workflow-git.png
