If you open a form via a Collector link, then leave it open (no save as draft or anything), then launch a second form it will keep the first open in the background. Once I close form 2 then I can see form 1 again.
What I am hoping for is a way to flip between those without saving to drafts.
We have to flip between a few forms at times and save to draft causes all kinds of issues with calculations that will not re-fire if the form was ever a draft. I get that for a save but I think a draft that is reopened should count as a fresh form so this seems like a bug to me.
