The app builder is amazingly easy, multi-featured but that all gets overshadowed in my opinion due to the weaknesses of the PDF Designer. I can build a very complex app in a hour (talking reference data, calculations, conditional screens and fields), and it will take me several hours to perfect the pdf.
The designer should work just like a Word file would. Copy, paste, align, text enhancements (color, style, font, etc.)
Your company is too good to have such weak product.
