Description

I created an option to add a transition (fade-in and fade-out) between the images of comments. Comments appear smoothly with the customizable length of transitions. You can set the length of the transitions in the range of 0-2 seconds, but I think anything bigger than 0.5 looks bad (best results with default value - 0.2).
