Hi, good catch, thanks for reporting this!
I'm not sure what is happening here, I'll have to take a closer look. Probably some dumb error due to the addition of a newer feature. I have an update in preparation, but sadly I lack time at the moment. I'll try to fix this in the next few weeks.
Regarding the source code, sure, I want to release it at some point. However, it's currently an awful mess and I need to refactor quite a few things . It's still a hobby project and I'm not a real programmer, so my code will look awful anyway, but I'd like to make it a bit less awful before that :)
