I would like to suggest/request implementing separate save pages for different player characters. I accidentally overwrote my first game when I tried playing a second character (habitual saving motions), and I'm constantly nervous that I will do it again. And it gets confusing keeping track of which save point for which character is which.
I also think it would be a bit cleaner to organize save entries in a vertical/box style, rather than horizontal strips, like many other renpy games use. They would save screen space and be easier to keep organized. Being able to add notes/save titles would also be useful.
I recommend looking at how the Innocent Witches game does it. It has about the best save feature I've seen yet. Something a bit like that would be awesome.
