At the moment, the only way I can maneuver items around the canvas is using the transform tool. However, the item I'm moving often loses its hard edge and the anti-aliasing takes over. Hopefully we can add this in later on, or possible a "selection move" tool that doesn't attempt to modify the selection in the end.

Yes the transform layer rely on Bilinear filtering and slightly "blur" the edge if the source ( your transform ) isn't pixel aligned for the destination.
My advice for now is to work in higher resolution ( if possible ) to minimize this artifact.

Thanks for the response. I'll give that a shot for the time being and plan my placement a bit more.
