This sentence is grammatically incorrect, too:

"With the new Layer Styles, a complete set of Liquify Tools, and support for the new OS X Mavericks features — creating advanced and polished compositions — is now so much simpler, faster, and more enjoyable."

I suggest something like:

"Creating advanced and polished compositions is now simpler, faster, and more enjoyable with new Layer Styles, a complete set of Liquify Tools, and support for the new OS X Mavericks features."
