Is there a way to quickly compare two flows? The comparison of xml files done by git is not the easiest approach.
You can use the notepad++ application, in that you will get an add-on extension to complete two files. That will give proper comparison between two files.
It is not yet natively supported, so @megharajky workaround is your best bet. You could probably also develop a robot that would take care of it.
Stay tuned thought, who knows what the future will bring
You can save the xaml files as text files and throw them in beyond compare. It works great for small amounts of comparisons but gets unwieldy if you need to do many at once.
