First of all, thank you for taking the time to reply.
True an ignore button can be easily abused if you’re not responsable and honest with it, I do use it a lot though mostly on mobile for typos, with the rule of never using it except for that. The thing is that after a while with KameSame I started to get used to the IME and started gaining speed, but that leads to sometimes choosing the wrong Kanji, I guess I’ll just have to be more careful from now on 
. Another possible option could be to make it optional somewhere in the menu, disabled by default so it won’t be there all the time.
Also about the timeline, I think you misunderstood what I meant, what I mean is a sort of timetable showing exactly at what hour your reviews will come, you can check this link to see the script I was referring to for an example.
Oh and thank you! for the fantastic app of course.
