I’m impressed that a feature such as the ability to divide the number of grammar points you can review per session isn’t in bunpro yet… I keep up with all my reviews, so this is not a problem of me leaving all of my reviews for the last moment. I could have 0 reviews then for the next Srs batch I have to do over 20. It is very stressful to have to do so many reviews in one go and it is the reason why I decided to quit wanikani (apart from mnemonics not working for me).
I suggest a limiter where you can max out the number of grammar terms you can review in one go. Personally, when I go over 10-15 I can’t focus anymore.
