I'm not sure if someone has already suggested this but I would find an option to disable the "Messages and Errors" window when launching a modpack very useful. I always close it as soon as its open because it always bothers me, and in the event that a game crash were to occur, I already know where to find the log should I need it. Other great launchers like the FTB Launcher (RIP) and the ATLauncher had these options, but my searches have come up dry when looking for one in the launcher settings.
