Just a couple of ideas to make life a little easier

The first one I got for ya, is automatic Smite selection for junglers. Imagine you are selected to jungle in draft mode. Once the game starts, you notice you forgot to take smite! I know it doesn't happen often, but when it does, it turns the game into a nightmare for the entire team. There aren't a whole lot of champions that don't need smite to jungle, but there ARE items that you can only buy if you have smite. It would just be a failsafe for the jungle role.

The second idea I have (this one is a little easier)... After you collect 3 key shard, have them automatically form a full key. There is no point in having to manually combine them, other than wasting time and interest in the loot system.

Thanks for your time.
