If you dont use it often, just every month or two, there is no need to have it tracked.
If you do use it then i think, it would be easy to just update it to another 30days, Im sure most things you will memorise in 2-3months which then you will not need to Track.
And if you do want to track it forever -- Favourites.
Becouse i dont have any disadvantage to it, and just becouse i do it the way i sead above, im going to yes this.
