On a related note, the reason changes weren't being saved more often is because when you do, OD takes you out of the eForm designer and you have to click the form again to continue editing it. Can there be two save buttons? One with "Save" that leaves you in the form editor and one that is "Save and Close" for when you are actually done.
updated: as you build out your form and it has multiple pages, when you save your changes and it takes you out of the editor, you have to click to open the form again, and then click as many times as needed to get back to the page you were working on to continue editing. It's not nice to work with.
Thanks!
