				Optimal thumbnail size
			 
			
			Leaving it here for reference. Most optimal size for cover thumbnail (/system/thumbnails) is: 217x330 Thumbnail with this size will have almost the same size as the cover of collection. There is 1px difference in height probably caused by rounding as my every try produced cover 1px to big/small. |

			Cool, so what we're doing in Calibre is still up to date   . (x330, keeping AR). |

			Well. Yes. Sadly size of covers produced by Calibre cover generator is hardcoded and they don't look very well on Kindle PW. |

			Yeah. It don't have size settings and it always create 590x750 covers. They look pretty bad as thumbnails. |

			Yup, probably because of the size of the library.png image, which AFAICT has no SVG counterpart.
