Can anything be done to further improve image rendering quality? (I can see work has already been done here #244).

My image quality doesn't change when I increase the resolution setting from 72 to any of the higher levels.

Here are two screenshots demonstrating the dip in image quality vs other browser image editing software (Photopea and Sketch.io):

In both cases the Minipaint resolution is set to 600 but as you can see that its image is fuzzier/more pixelated than alternatives. I am working with a 2560 × 1600 Retina display on the latest version of Chrome.
