Ratings and reviews

So idk what happened, but there used to be a tab for switching to the view that allows you to adjust dora, honba, and winds. It's completely gone. I actually came here to say that there must be a bug, until someone else at the table with me figured out that you have to swipe to get there instead. There are no visual indications for this--if I were a new user, I wouldn't even know to look for that page. This is either a bug, or a terrible, terrible design decision.

Swiping to find how to set dora/seat/wind/honba is very unintuitive. I thought this was a half baked app for sure. Luckily I read other reviews that had the same issue. This really should be addressed in a design change or explicitly noted somewhere on the opening screen. Besides that though- I plan on using this app whenever I'm playing

Great app for score values, one small nitpick is that i can't seem to find an option to specify that the win was through ron, not a self draw. Otherwise, really great app and really useful for beginners/ intermediate players.
