Media Library is awesome!

1- I love how easy it is to navigate.
2- I love how it saves what you are reading and you can go back to it later.
3- I love sorting by level and content type.
4- I love the volume of content. There seems to be a lot there.
5- I love how it shows the progress by page number

Seriously, this made my day. This is above industry standard.

PS:Number 2 is the best feature, which is why I bolded it.
