The popular Barnes and Noble Nook Reading app for the iPad 3 has been updated today and gives you a hefty dose of retina support. Much like the Kindle and Kobo app the bulk of the update gives you crystal clear text that makes reading a bit more easier then before. One of the facets of this update that really kick things up a notch is the new highlight abilities. You now have a MS paint or Adobe Photoshop style color palette that you can choose from tons of hues and different colors. This will allow you to have more flexibility in the colors you want to augment your textbooks or ebooks.
There is also a new ability to read in landscape mode with column support. You can elect to read with one or two of them to make reading a bit more enjoyable.
