Font Browser on OSX? myfonts.com has a create feature where we can choose sample text and selected size while browsing hundreds of fonts. This makes my life much easier when I need to decide which font to use in my design. I like to know if there is a desktop application that does the same thing (either system app or App Store apps that runs on OSX).

For those who don't know what I ask, I did a screen shot to demonstrate what I meant by 'where we can choose sample text and selected size while browsing hundreds of fonts'.
Font Book in your Applications folder. Comes preinstalled with Mac OS X. Choose Custom (under the "View" option on screen top menu bar) and then type the text you want to preview. Then you can cycle through your installed fonts using the up/down arrow keys and the preview will display your custom text in the highlighted font.
