Changes are... eh
I enjoy browsing pixiv, but the new interface makes it way too easy for me to accidentally bump the like button on some random thumbnail while scrolling through a tag.
I have mixed feelings about the new homepage. While I appreciate the app trying to show me things I might enjoy, it seems to be using information from privately liked images as well, which kind of defeats the whole "privacy" aspect if related images are right there when you open the app.
