Ingame Tab Hero Order
First thing I do when I enter a game is hold Tab and move the character icons in the order:
Top Lane Top Lane Jungler Jungler Mid Lane Mid Lane ADC ADC Support Support
I feel like the game should do this automatically for you. This helps everyone compare lanes against enemy lanes. You can easily check your CS against the enemy's CS in the same position. This shouldn't be too hard to create too; seeing as you can queue up as Jungle/Top/Mid/ADC/Support now. Something simple but could help.
