Good graphics add-on for FCPX?

[KiterTodd]

I see a lot of videos online that have very slick looking graphic overlays to add a professional touch to projects. These are either floating moving graphics/text, glint highlights that pop out from reflective surfaces (like when someone puts a starburst on a smile) and hand drawn outlines surrounding objects in video. An example would be a car driving and a line is drawn around the front grille during motion.

I know you can import graphics with FCPX and add some movement, but is there an add-on application that makes this easier?

Would like to stick with FCPX for my editing, but was just looking for suggestions to kick it up a bit.

Thanks!
