1. Does your plug put uploads into separate folders, 1 folder viewable for posts, and 1 folder secure due to sensitive information provided by clients. I have found an annoying work around with free plug ins by physically transferring uploaded files via WP-Visual Form Builder to WP-Filebase folder which you can make secure. You have to be really careful using WP-Filebase because once you make the permissions for a folder private to admin and contributor, it seems irreversible. I had to re-upload my uploads folder from a back up of my website because I accidentally made all the folders private, and none of the images on my website would show up, even after I tried to change the permissions.
As well, for long forms, can form users save their form progress, log in and continue form progress at a later date/time?
I think these questions were answered, but I can't access the answers since I don't have a license.
