There's no mention of the new icons at all now (not the library).
Superficial, but will probably make many happy.

This should move down, since it's very unpopular.

It's not clear on a quick glance that this is a TR thing. (Also,
"customize" sounds a little like underselling it, but maybe there's no
good way to talk about what can be done with it.)

Maybe move this one up a little?

"up to 4 times faster" sounds fishy -- I think that just "faster"
sounds better. Also, should move up.
