I started thinking about the next thinForm and I thought I would bring up an alternative:

What about using a free form designer, like Microsoft Visual Basic or C# Express IDE's for making the forms?
Then the new thinForm could be written to use the form files generated by the MS IDE to generate
thinBasic scripts. or perhaps the script generator could be written in MSVisualBasic or C#.

Let me know what you guys think or if you have any other suggestions or ideas.
