Yay! Honestly the same thing happens with my save slots when I'm play testing. I often try to keep different playthrough separate so I can refer back to them but it always ends up a mess. ┗( T﹏T )┛
This system was born half out of wanting to re-use the design I did for the gallery and half out of a conversation with two fellow devs when we were discussing non-standard Ren'py UIs.
And it just hit me how *useful* this would be to have different pages for the characters. Windchimes was the one who mentioned being able to add additional save slots though. That is honestly such a cool feature. ╰(*°▽°*)╯
