it would be very nice if you can add a time on a task when it should be done. i dont know in how far this should be possible, maybe only game time (1sec = 1 min in game) but if it could be real time in [sec-min-houers-days-weeks-months] thet should be fun to do tho becouse you can really keep track of how long you still got for something, it could also be used for some kind of [after 2 days and 3 houers my iron patch will be gone] effect.

thx for reading and im sorry for all the typo's/grammer errors/misplaced words.
feel free to contact me on discord if you want any help on any kind of graphic design like the icon or illustrations.

Hi,
thanks for writing.
There is https://github.com/JonasJurczok/factorio-todo-list/issues/30 which describes a timer for tasks. Basically a configurable deadline.

Unfortunately time in factorio is relatively complicated thanks to UPS.. So whatever there will be will be very simple. I'll note down that this feature is actually requested. Thanks :)
