Great idea. Another good idea would to be able to have pages that you could scroll through similiar to your masteries and runes. 10 pages in the client would be enough i think and if you could have say 3 pages in game that you picked in client it would help alot. IE having a page for a tank build, an off tank build and dps build.
This would really enhance alot of peoples gameplay due to less time shopping.

Updated thread and image.

This is very good idea. I hate the item shop in LOL. I Want hotkeys. Is so hard to navigate, and now in dominion where every second counts, its lethal sometimes.

I would love to have the option of a HoN mode where you can put an item in queue in your buying list. And everytime your champ goes to the champ, if you have gold available, the item is automatically bought for you.

Hotkeys would be good to use, indeed.

Bump.

Bump this indeed, I like the idea of a revamped shop screen indeed. I especially like the idea of custom recommended items and the idea of easily being able to see what a basic item builds into (EVERY item, not this "Oh, I clicked on the boots and it gives me everything except ninja tabi" stuff). Thanks to Fuskamo for that shop mod link.
