Now that I had time to work on some animation, I did notice that while it is generally much better to work on skeletal animation in pixelover some quality of life improvements would be nice. Such as deleting or moving multiple key frames at once, now these are made one by one. Automatically addition of key frames, such as you are in animation timeline, and you slide the current frame, and you move a bone, I wish it would add that bone automatically into the timeline. Adding and managing multiple bones in the timeline is a bit of a hassle and I wish you could organize the bones there, since otherwise they are in the order you added them in.
But other than that, I have managed to rig a skeleton and made a simple idle animation. I wonder how altering the skeleton images and replacing the bone images will go. As I am hoping I can make the animations on the base skeleton and later on just replacing the images of the skeleton with the new images. But that comes down to line, so far bit janky but otherwise good. I hope this feedback helps.
