Do you know when you install a couple more mods for say Minecraft, then when you boot up it crashes? well here is the semi-solution to your problem. make there be groups of recently installed. When you play initially it logs the mods you have, then if you add mods and a crash occurs a question mark or warning sign shows up on mods added before the second boot that may or may not have caused a crash. In simplest terms Log mods on Initial boot, save list, when mods are added keep the list, when relaunched and crashes show warnings on (maybe) incompatible mods that may have caused the crash>do this by checking old list with new list of mods. Then us, the user, can go by trial and error and find the mod causing the problem, and we will all be happy because it helps everyone involved, the user, the mod creator, and maybe people who make fixes for mods.
