I'll add locking custom objects to my to-do list.
For disabling hotkeys, a workaround could be to set them to a key you wouldnt use like F12. I'm not sure if I'll add something like this, but will add it to the list.
More control over cam transitions and model squish is a good idea.
Ooooh That could be interesting. I'll add sticking objects to the list
Open SeeFace actually does have expression detection built in. It'd just be a huge undertaking to implement and the expression detection requires training on the user's end by making and holding faces for a long time and tbh I've found it to not be very accurate in my own testing.
Thanks for the feedback!
