Would it be possible to add something to calculate the total filament length used to date on the current roll? I would like to know this to estimate how much filament length I have left on a roll to so I can estimate if I have enough left to print when I'm close to the end of a roll.
Also, would it be possible to add something to allow a manual entry of the price paid for a roll in order to get a more accurate cost estimation of a print?
