Dirty Git capture

[rahuldave]

Is your feature request related to a problem? Please describe.

In dev mode you often try code before a commit. Spock already saves dirtyness, but if dirty, it would be nice to save dirty files. Either directly or perhaps via a custom ref.

Describe the solution you'd like
Something that captures dirty files somehow, either in git or directly

Describe alternatives you've considered
One could always commit...
