Hi @Argos_Rumpwhistle, thanks for your feedback.
For an offline local use, I plan to make a desktop version of the app.
For the addition of functionnalities, I try to keep the format as much consistent as possible so it doesn't add more complexity. So if you don't use it, it shoudn't be to much of a bother.
I was planing to add music support but the thing is, when you complie you currently insert everything into a single file, pictures included. With larger file I fear it to become quickly a size problem...
I'm a bit confused by what you say about decision tree. The tool already allow to make choices. But maybe I'm missing something ?
