#1780 Speed,Copy and Loop options
I think adding the options of copying or reversing frames to create loops would be a nice feature that I notice there is to problems when exporting since Either some animations don't loop back or goes too slow after extracting and I try to extract the animations of games where you use the mouse or click to move certain speed so I believe this options would be a way of helping more effectively
