I actually like the animations, but think they can be improved.

Some small notes:

  • animations are too slow -- they don't seem janky, but they lag - I am on a Pixel 2. On my Moto G, returning to a tab from home is very stuttery, however. On my LG G4, the fading effects also look very slow
  • when moving to the home screen from a tab, the page seems to go white immediately as the animation begins, which feels kinda disconnected from the "minimize" action that this tries to portray. Instead of making the page white and then performing the animation (if this is what is happening), the page should itself be animated, like the genie or scale effects in macOS.

@yoasif there is quite some fragmentation in the animation. Not sure what is the technical term https://imgur.com/a/A7iqJ5P

Looks similar on my device (HTC U11, Android 8.0). While I think the animation from the tab to the home screen looks okay (only a bit annoying after a few hundred tab switches...) the opposite animation from the home screen to a tab looks not good, there is some kind of flickering.

Thanks @andreicristianpetcu for raising this. We will address this in #1289
