So this still hasn't been resolved? What a pity, this is such a silly thing and must come up so often.
I want to draw shapes that have a fill, but no stroke, yet I can only see what I have drawn once I lift the pen. It's ridiculous that I have to include a stroke color for these objects and then later go through and remove the stroke color for each one.
I can create all of the objects on the same layer so that I can select them all simultaneously and remove the stroke, but this is a hack and shouldn't be necessary.
Please fix this, Serif! I absolutely love Affinity Designer otherwise. It's a great piece of software.
