I've used the MyM-Launcher for a long time now. It works really well, the only small annoyance for me is: I'm starting it via a terminal, so I get the Minecraft output there (on my Linux-terminal of choice) I would really like a command line switch (--noterminal / -nt or something similar) to disable the buildin window for "Messages and Errors". If this is really complicated. --autohide could be introduced to hide this window every time without having to click "Hide Window".
Sorry, this is not possible. Due to being trivial we won't add it. If you really want it and know some java I could send you the repo and you could submit a pull req.
I've added a MergeRequest against MineYourMind/launcher · GitHub . If this is the false repro then please leave a link to the right one. I'll mark this as done as it isn't good to communicate the same thing on two platforms.
thanks, I assume you compiled it for your self, so the update can wait until we have finished a few smaller planned changes?
