Editing itemsets/queue in-game

According to the site gameplay ideas should be posted here. If this is the wrong place, then please move it or let me know.

I'm relatively new to the game and I often don't know what to buy, so at the start of the game I may ask what items I should go for. People usually tell me a bunch of useful items, but I can never remember them. It would be incredibly useful (at least to beginners) to be able to store a list like that. The way I fix this now is I keep asking "what item should i go for next?" during the game.

I guess this could be implemented more or less like item sets, except I need to be able to edit them in-game. I like playing new champions and often don't know exactly which one I'll be playing until the rest of the team has decided, plus I like to change my item set depending on the enemy team. From a development perspective this seems like a rather large change and I doubt people have enough time to fully manage an item set while in-game, so...

An even cooler way to implement this would be some sort of item queue in the shop, where you can place several (up to 6?) items. An item queue could be easily set up or adjusted during the game (maybe drag/drop or just click an item to queue it?). Clicking on an item in the queue would then open it up the same way as clicking an item in the shop would. There's even room for something like an item queue on the right side of the Buy and Undo buttons (actual items are shown on the left, but there's a large empty space on the right). This would even give me the option to think about my next item and queue it without losing sight of my almost completed item, this is useful when you're waiting to be revived. It would also allow me to keep track of items people advise me to get at any point in the game.

Do you think this would be useful? Or do you have ideas to improve upon this?
