use case: When building a flow, I sometimes copy another flow and update the necessary stages. Thereby saving myself the hassle of recreating the entire workflow. However, since you can't save a workflow with errors, you need to make all of the edits in one session rather than saving with errors and being able to incrementally correct as time permits. Very frustrating!
Solution: Allow saving but prompt with something like "this flow contains errors do you still want to save?" if there are errors. Or save as a draft.
