pre 5.0 update, you used to be able to hold the command, control and alt keys to quickly translate and rotate your models while holding these keys down in OSX.
in 5.0, the interface has become terribly slow, and sometimes becomes completely unresponsive in fullscreen, requiring you to exit fullscreen for any of the GUI to update, most notably when going back from a generated gcode preview to model placement and profile selection modes...
to be honest, everything was unanimously better in 4.x not sure why im still using this software, but i keep paying for the illusion of quality.
