I have been using Versions App for a few months now and I am loving the simplicity of the app. However as much as I love it I kept going back to my old svn client when I needed to branch or tag. I never could get my head around how it was done in Versions and the user guide wasn’t very helpful to me. Although it does explain it clearly. 
So if you use Versions and want to quickly create a tag just go to the remote svn folder. Hold down the option key and drag the trunk into the tags folder. Next a dialog prompt will display and ask you for the new folder name and finally to commit it. The tricky part for me was the option key. I seemed to always miss that step.
