actually the #1 criticism i had has been fixed since the last time i made reading progress: one-click progress updates from Home. I launched the app on my phone and bam, it's right there!

I'm not sure there is anything I'd improve. I recall when I started creating a list of Akutagawa Prize winners in translation, it was a bit painful because I had to input a lot of ISBNs for rarer books. Also I struggled for a couple books with picking the right version so the page count was correct.

But I haven't done either of those in a while since I haven't read more rare stuff in a year. Possibly they've gotten better, too.

not OP, but sometimes I add the ebook version to my library even if I never use them. To find it again and fix it, sometimes I need to scroll through the years of read books to spot the tiny icon that distinguishes the version of the book. It would be nice to have a simple filter by book type (physical/ebook/audio) in the library page.
