@davidrevoy and does “Spread” expand the fill beneath the lines (if that makes sense)?
@tangocharlie
If you want to expand color fills perfectly under the lines, using colorize masks works better than the fill tool
@davidrevoy
@redj @tangocharlie True, I made a video about the colorize mask https://www.youtube.com/watch?v=HQdx6H9BIGs , this feature is for sure (as said by Redj − hello! ) a bit better at finding a middle ground under the thickness of the line-art. But it's also fully aliased by default, so an icing on the cake after a flat aliased coloring using the Colorize Mask is always a GMIC filter (in Krita) of antialiasing, or a Gaussian blur filter of 1px. In case of transparent line-art (or penciled) it works really well.

Hi David
Personally I like that the flat colors are aliased: I only use my flat colors layer as a selection source, to quickly select each color zone (so I can paint effects on another layer), so having aliased flat colors mean cleaner selections. And since the lines on top cover 99% of the artwork, it's never really visible in the end
