Nice.
PS: the app does weird things when (after you generate a character) you keep clicking on the checkboxes, for example adding, removing, then adding again the “extra flavours”. However, I suppose it isnt’ built to function that way, simply I love to tamper with it and find out how the things can go badly 
Anyway, I don’t know if you already know the side perchance.org
In the past I found it cool for generating things, and build some easy generator using its “programming” rules.
For example, here one of the first S&V generator I found there:
https://perchance.org/pdq8o9qplc
The cool thing is that you can go into “edit” mode, and give a look to the lists they used, and the structure of the generator: this way you could easily expand your own creations, or simply find nice inspirations.
