Hello, thanks for your message. I'll forward your message to the coder, see if that's something we could do in a future update because I don't know either. The fast forwarding should work no matter what if you've triggered off "stopping at unseen text" in the settings. The game isn't "smart" enough to understand and remember what you read and what you didn't so this is your best tool.
That's also why we have the "skip" option that immediately brings you to the closest choice or to another day without having you to read through everything and yes, I know. You asked if we could get something in between. I'll see if that's possible or not.
Edit : Your request is possible, just got back from asking our coder about it. I can't say when, but I will keep it in mind for future updates.
