Traditional animator keep fliping the last papers to see the flow of the action, like this https://youtu.be/cHbA6lG79Eo?t=7m12s
I think this is more a strait ahead thing.
So, I would like to request a feature that allaw me to those a certan number of frames that i can play. Its like the interval play option, that i have to use right now, but you just choose how many x frames and than the last x frames are the ones that will be played. Probable would be better that insted of the frames, you choose the number of drawings, but that is with you guys., i think.
Also to complemet this feature, and is something that i think that shoud exist anyway, is when you play the play button and the animation stop, insted of the frame that you can draw now is the last one, shoud be the one that you was when you played the animation. In other words, if my animation have 20 frames, but i was fixing the draw of the frame 4, after i hit the play button, i shoud be back at frame 4, not on the frame 20, so i can continue editing the frame 4 if i need.
Hope that i got this english thing right, so you can understand me
