Hey there - that's a good idea, we can change the save folder easily enough. The encounter library is going to be on that same screen as the encountered characters - that's already in the pipeline. And as for the reason - a game log was implemented in version 0.1.22.0!
We have a git repo up on github (https://github.com/majalistic/tales-of-androgyny) and we've accepted contributions before - if you want to chat with us about it, we've got a discord server (https://discord.gg/UuGE3uv).
