UI and manual are more hobbyist than professional level, lacking a clear didactive concept
I don't like tools that come along as freeware and turn out being a shopping place for unreasonably priced extensions. This software is not at professional level, the UI even does not provide any option to set the character fonts. The UI look is cluttred, lacking e.g. icons designed for this UI. Localization does not work, translation is poor. Same with the manual. No red line in the manual, images (gues made by powerpoint) without reference, not correctly sized. Tha's less than undergraduate document quality. I have no motivation to look further into this product, as the first impression is so negative. Might be agood idea to spend time on UI and manual before developing a bold business model. For the manual, I would start defining a design style guide, e.g. have all images in same scale, in some standard sizes that match the text.
