 Adds various useful tools for pixel art to the Extras tab.
 
 ### Purpose
-This extension is used to fix non symmetrical pixels in ai pixel art through downscaling.
+This extension is used to fix asymmetrical pixels in AI-generated pixel art through downscaling.
 It also can be used to limit color palette and clamp grayscale values to get more stylized results. You can also use the rescale feature to get a higher resolution image (best for preview on the webui canvas).
