[FEATURE] improve workflow versionning

[loicginoux]

Is your feature request related to a problem? Please describe.
For testing my workflow with a real case, I need to deploy my code, so everytime I test something I create a new version of the workflow. My workflow ends up with lots of versions. Most of them have bugs or are here for testing/debugging
Sometimes I want to go back to a specific version but I can't remember which one it was, it can be 10 versions back or more, it's hard to identify versions and difference between them

Describe the solution you'd like
Something closer to real code versioning, so more like git commits:

• being able to add a comment to a version. This would be a "quick win", as I could just tag a revision that I know is working before creating more revisions, So I can easily come back to it even if I created many revisions after.
• Nice to have: being able to compare 2 versions of a workflow

@loicginoux if you could store your workflow in a Git repo, such that you could use Git to manage this, would that work?

I like the idea of the tagging, etc., just curious if Git would solve the use case for you.

Yes that’s another solution, that would work as well. Thx

Ok great. I added your request as a comment on #220, where we're tracking that. If you don't mind, go ahead and follow that issue for updates.
