Using WebP can really reduce the image size, and thus shrink the size of the EPub/CBZ
Ummm... you did notice the line that reads "W3C Working Draft 06 April 2021"?

You might also want to check Is WebP really better than JPEG? before repeating the 25% to 34% size savings claimed by Google.

In December, 2020, I did some testing on my epub collection with their average 1000-1125 x 1500 cover images which are compressed using the Mozilla JPEG compression. Using cwebp to compress 10,000 of the original cover files and resize them to match the current cover files yielded an output directory that was 5% larger than the directory with the mozjpeg compressed cover images.

As for supporting CB7? In compressing image files, I've found little advantage to using 7Zip's 7z archive over a more or less standard zip archive. The image files are already compressed and adding them to an archive does not yield much extra compression. In a quick test, I compressed 20 images from my camera. Using 7Zip's 7z archive format with everything set for maximum compression, the output archive was 197,101,971 bytes while using 7Zip's Zip format with normal compression yielded a 198,244,218 bytes output archive. I'm not sure if the time to create the 7z archive justified the 0.6% file size difference.

Please make it easier to invert text on the Forma. As it is, the user has to activate developer mode, then go to settings, device, developer mode, which takes time. The inverted text is much much easier to read in a dark room at night. I use it every night. It works much better than the similar feature on the Amazon Oasis, which is far too dim.

If you install NickelMenu, it is a bit simpler.

+1 for NickelMenu. 2 taps from the main page, and 3 if you're reading a book.

The following lines in the conf file will add "Invert Screen" to NickelMenu in the main menu and reading view:

menu_item :main :Invert Screen :nickel_setting :toggle :invert
menu_item :reader :Invert Screen :nickel_setting :toggle :invert

The ability to lock not only portrait/landscape, but also button placement (left/right or up/down), in effect disabling the gyro sensor completely.

The Aa settings get saved after you apply them. So when you open an eBook you've not opened before,the settings you last applied will be what's used.
