With MineMenu 1.4.4B9 on 1.10.2 it appears that any keybind that would open a new window/overlay simply does nothing. For example, opening JourneyMap or Psi's manual. Thanks.

Thanks for reporting!
This is a known bug, just simply don't have time to fix it currently. Will get around to it eventually :)

Any chance of this getting fixed? Trying to set up the mod to simplify a lot of confusion with keybinds in Sprout, and a lot of what I'm trying to do outright doesn't work because of this bug.
