It might be nice to have the keyframe mode carry on between consecutive keyframes, rather than it be reset to 'Smooth' by default.
I've been trying to emulate a basic stop-motion cut-out effect using the 'step' keyframe function (as the 'smooth' setting adds inbetween frames - which look fantastic, but can give the animation an inhuman feel). It can get frustrating that each time I want to generate a new keyframe, that I have to manually switch it to 'step' mode.
It would be nice if, when I set the first frame's keyframe to 'step' mode, that Moho then assumed that this was the mode I wished to continue working in throughout the piece, giving 'step' as the default next time I created a keyframe in that channel.
If I did then want to change the mode to 'smooth' for, say, a steady camera pan across a backdrop, then 'smooth' could be chosen and this would then be the default keyframe mode until I changed the mode to anything else.
Of course, being a new Moho user, there may well be a way to do this that I've overlooked. In which case - sorry

Cheers
