Hey, I have been using bunpro for a couple months and as I get further along into new stuff. I find myself learning a lot of grammar that both my teacher and Tobira tell me that it’s formal or only used in writing. I would love a system that would make sure it was crazy obvious when reviewing and learning that the grammar point is 硬い. Not just hinting that it’s an honorific but reminding you that maybe the grammar point is very stiff/formal.
Also it would be great to do the opposite to and put the same for very very casual points. Maybe after add a filter where you can review/practice only casual or formal.
