Here's an idea that was brought up a while back but didn't see as much traction as I would have hoped:
https://community.marketo.com/MarketoIdeaDetail?id=08750000000Hi6MAASThe ability to add multiple logic funtions to a particular flow step would make life on our end much easier. For example, a flow step - 'Change Data Value' if 'Has Opportunity' is 'True'
AND 'Opportunity Stage' is '1, 2, 3, etc' - Change Lead Status to 'SQL'.
