Initial compositor #gesture code is now merged onto #phosh and #phoc's main development branches. There's some visual and structural stuff to fix before the next release but I'm running it since weeks now and it proved to be pretty stable.
@Alexmitter did you try the current code? They already look different there. The issue in the video is not so much animation speed per se but rather the easing function and that we want to pick up the swipe velocity.
