I was never bothered by the animations, but was livid when they redid the desktop thumbnails, and offered no way to always show the preview by default. You have to mouse up to them to get the previews.

It didn’t seem to bother the rest of the Mac world, but I used to organize my desktops in a chaotic way that worked great for me, and the ability to see the preview thumbnails as soon as I popped into mission control or whatever they call it enabled me to quickly go where I wanted to after a quick glance. I used to rename entire desktops, too.

The whole thing instantly became worse for me when they took away my ability to name your own virtual desktops, and added the extra speed bump of making me mouse up to trigger the previews. I’m still bitter about it.
