I think they just need more time, and the setting's dont seem changing because i cant reload it in the windows version. In the web it works almost perfectly. Just that i'm not sure if they evolve but I'm gonna give them much time now.
The diversity plot _should_ show how many variants a gene lasts over time. In the web one, because of perf you cant have alot of population and steps(mating to make new ones) it looks kinda flat :) If you increase the population and steps substantially, it will run _much_ slower and take alot longer for a generation, but you should end up with more diversity.
Id really only recommend doing this on the desktop version :)
I'll check to make sure thats all working properly. I havent looked at this for a while.
See above note. I suspect it cant write the inifile. If you want, you can edit it yourself. In the data folder there is biosim4.ini. This is what the app uses for its data - changing it here is the same as changing it in the ui.
Another alternative is to give the app write permissions (this might be why your settings dont save).
