hi, I see that the grade buttons arent accurate, in the way I pressed a button 
on 10/03/13 (12,2 months) and then checked when it is going to come up again 
and it was somewhere around 25/02/14 it is not a big issue but.
Another question is,why there is gone fourth button from anki style grade 
button, and why now I see 3 months instead 90 day,it think days where better, 
it was giving a better sensation when i saw 90 instead 3(:, and i would like to 
be able to change colours of grade buttons.

1. The interval is not exact. If you want exact interval, go to "Options", 
customize algorithm, and turn off the noise there.

2. It is kinda hard to satisfy different users. I use day/ week /month to 
address a feature request suggested several times by users. For me, it is of 
course harder to do than putting just plain day there. IMO, I do not really 
care about the exact date. The grading should be not based on the interval, it 
is based on how well you remember the cards.
