Exporting sequences of frames for 8 directions occupies too much memory during runtime. It would be great if exporting components and skeletons were possible. I am willing to pay extra for this

Please elaborate more on what you are planning to do, I don't really understand.

We are currently doing our best to upgrade the tool to newer version with skeletal animations at the base of the program. Right now the base are sprite sheets. No skeletal animation animation data exists within the current form of the tool. It exists externally as that's how I create the sheet bases. Maybe that helps shed a little light.
