Three Things would be nice to see to ease workflow:
-The ability to detach bones from their child sprites just to reorient them and then reattach them. This is just an issue I had when I put sprites in as negative x or y values as part to the animation and then the bone was facing the wrong way. I get that the bone can have the x and y value inversed as well but that didn't apply in this case
-It would be good to be able to animate certain bones or sprites independently from the main keyframes. In fact i feel think that the main keyframes usually hinder my work and always have the "only show selected" box checked in the timeline. Currently if you need to go back and change something, you're forced to go through every keyframe and change it which can quickly become a mess. This includes adding a new sprite that you want to be there through a portion of the animation. Or if you want to animate separate parts of the entity at a time you're hindered from going back and changing the other parts because the timeline added keyframes to every part of the entity. Where ctrl+shift+v is the hammer, I think a scalpel would be nice as well.
-copying in objects from outside frame 000. If I currently try this, like an arm from later in the animation made of different sprites it flies off to some random part of the animation with a different orientation. I guess this is a bug as well but it doesn't seem to bother me because it's about needing to paste something. The image is of this bug.
