On the next update i would love to see two changes to make searching more effective. First it would be nice if already purchased books dropped to the bottom of a search. it can be super annoying and time consuming to go through multipe pages of free book purchases to get to ones you actually can purchase. second i would love to see a box added to each item book app etc (similar to add to wishlist) saying exclude from future searches. that way things people dont ever want they wouldnt have to wade through each time. This would be especially beneficial for customers like myself who always just browse for things of interest.
The first of these could be done in a search options drop down menu ~ clear options, exclude your books, released in the last month, etc. The second is something I'd like to see the user interface just like that ~ a check box by the listing where you can not see that one again. Netflix has it.
