Couple things that I noticed:
- The main page looks a bit cluttered, but since I never go there, I don't really care or mind. I don't really see any need for "Latest comments" and such. But I frankly don't understand what is the main page for anyway. I have my Follows page bookmarked so I always go straight there.
- Big issue I have is with the navigation bar. You see, I use 13" tablet (2in1) in portrait mode and right now I can always see the Follow button on the navigation bar ( I had to make the website like 80% of it's size, but it works fine). This is useful when I finish reading latest chapter of something, I can easily click the Follows button again and see what else I haven't read yet. In V3 the buttons are hidden behind the
hamburger button, requiring me to do one more click. If I resize the page to 80% like I'm used to, the sidebar with the options shows up on the side instead of the top. This is really annoying.
- Another issue with size is the Follows page. I will let the screenshots speak for themselves
https://imgur.com/a/jGi5lHm (dark is the current MangaDex, white is V3). Issue is obvious. There is padding all over and the text doesn't expand the rows. This also illustrates my previous issue with the navigation bars.
- And lastly, I'm not a fan of the changed reader behaviour. My usecase is such that I often hold the tablet with my left arm, so I really can't touch the right side of the screen to move pages. I much prefer the old system where tapping anywhere would go forward and swiping back would move backwards.
- The reader UI could use some polishing as it feels cluttered, but it's not too bad.
- And then there is the Edge/IE bug where reader doesn't work at all. I would be great if you could fix that, though I understand old Edge/IE users are in minority.
