Been loving my time with Pixel Over! It's everything I like about Adobe Animate in a convenient pixel-art friendly format.
My one gripe would be that, as a pixel artist, it would be really nice if there were something akin to Blender's Knife tool, or Animate's ability to break apart BMP's. It's not like a huge issue, since I can do that in whatever program I'm using to draw in, but I feel it would make the process of preparing assets for Bone animation a lot smoother. Just paste in a frame, cut it into parts, and get to animating.
Not entirely sure how feasible this is in the engine Pixelover uses, but it was an idea.
