It would be good if the Habbit tracking had a default state of unknown and
one press marked it complete >
Another marked it as Not done (as a confirmed no) >
Another returned to unknown.
Good as sometimes at the end of the day you can't recall exactly if you failed to do a time sensitive Habbit or not and while both unknown and Not done will break a streak it is also a great way to keep track of if you have been keeping on top of marking off habits.
