Hi, thanks for asking. Yes, a Pro version is on its way, slowly but for sure. The pro version will be independent from the free version. Both, free and pro, can run side by side.
The main features are a WYSIWYG Editor with customizable Toolbars, col- and rowspan, import data from CSV, choice field of classes independently for the table, cols, rows, cels, thead, tfoot. In the field setting you will have a pre-definable table in detail the same way you edit a table, min and max rows and cols, defining of class choices, enable or disable features separately for the table, cols, rows, cells, thead and tfoot.
I have no timetable for the release. Some challenges are still pending and decisions to make. A message will appear in the free version, when the public beta test starts.
Cheers,
Johann
