Update by Robby: This thread is a bit out of date, so I am popping in to update it.
This module is no longer free, but it is available still through Fotoplugin’s rebranded site: Beaver Lodge.
If your like me and work on big monitors, then the small lightbox for the module editor in Beaver Builder must cause a minor frustration?
With my new plugin, you can now set the size of the form, change the transparency to see things below as well as alter the font size and color, all from a simple settings page.
