Currently the PS4 has a library tab that lists all the games a user owns. I would like to suggest building a similiar setup on the PSN with a tab to sort through each console and sublist dlc underneath each game. This would allow users to easily view owned items and download them to the console. Currently the PS4 is the only one keeping a decent track and user friendly viewing of our library, and the store website is due for a touchup to match. The long download list shown on PS3 and Vita (which was supposed to be a next gen console btw) isn't that great when you have to scroll through hundreds and even thousands of items both game and dlc and the like. While making a tool specific for these isn't as top priority, making an excellent home hub on the store that lets us properly view and manage ALL our owned products is indeed a top priority functionality and should be added ASAP.
Please consider this.
