SUMMARY Krita's Selection tools work well for normal art, but they are not pixel art friendly. Only Rectangular Selection tool can produce pixel-clean-cut selection, while the other three: Ellipse, Polygonal and Outline, all have interpolation on the edge of the selection. The interpolation creates transparency and thus generates unwanted colors to pixel art's fixed and limited color palette. Pixel artists are forced to use Rectangular Selection tool for color safety which greatly impacts efficiency. Is it possible for the Selection Tools to have an option like the Transformation Tool's Nearest Neighbor algorithm, so that the edges they produce can be a clean cut?

That is already possible. Select the raster, not the vector mode of the selection tool. Uncheck the antialias checkbox. Use cut or copy sharp in the edit menu. Krita remembers those settings for the next time.
Yeah I can't put my finger on it but I did feel I was missing something...sorry for the false alarm! On the other hand... As we default to Vector Mode, where the Anti-aliasing checkbox cannot be seen, the discoverability of this function has become an issue. I know I was dumb and all that, but the fact I missed the checkbox still reflects the difficulty that new users would have finding the function. Do you think we can add a note at the bottom of the Selection Tool's options, saying: "Note: You can only turn off Anti-aliasing in Pixel Selection Mode"
