You can edit the length of the boosts. Just put on a boost and make sure it lasts a little while so you have time to go and edit the json file. Then search for the amount of the boost, and then either right after or before that should be the duration. You can set the boost amount to 1x10^100 with a duration of the same number of seconds. and it will never run out, but you will also be able to max any mine in a mater of minutes if you use super cash to unlock barriers. You can also edit super managers and resources needed to upgrade them as well. These are all located near the bottom of the json file so they are pretty easy to find. There is also right near the very bottom that says something like haspurchased..... that should be no if you have not and yes if you have if you want to buy any any of the in app purchases that give a perm boost to production of offline. I would advise trying to do it on a PC with wordpad or a tablet as you need to be able to read it all. I would start at the bottom and slowly read it going upwards if you don't want to search and who knows what else you will find in there.
