That is the biggest rub for me so far.
It leads to more clicks and more forms popping up to get things done. For many of my customers high-speed data entry is very important.
Plus, the aesthetics of it: no dropdowns, no checkboxes, no radio button groups etc. I know beauty is in the eye of the beholder. All those purpose-built controls that we see in every other app are swept aside for what? The choice of one developer, and in service of the bigger goal of reusability?
I'd like to be blown away by what this approach makes possible, and I'm sorry, but I will watch from the fence from now on.

I just tested the sample file and I couldn't make it work. I put all files in the same folder and then a form with a message appeared. After discarding the form with the message, another form opened with 3 buttons. Clicking on them returns error 3043.
A few thoughts about the situation:
1. You've said it's quick to develop with it, but it remains a mystery how that is done.
2. There is a language barrier to overcome because some things are in english but a lot of others are not
3. I could attempt to fix it, but since the project is locked, I can't and shouldn't if I tried to unlock it
Given Tom's and Edgar_'s responses, I return to my original comment. Take this as an attempt to give constructive criticism as I offer you a direction I think you need to go to improve your presentation. If you have inadequate documentation, your product is generally useless to anyone but yourself because from the limited sample of some pretty high-powered guys who tested this sample, you are the only one who can make it work.
