Are you really that lazy? It seems you need to prioritize your favorites better.
I have bow > dagger > 3 shouts > potions
All you really need unless you're a mage which at that point I can semi-understand but truly, you only use shouts so often that it seems highly unnecessary to do this.
I have 3 swords there (2 primary, 1 soultrapper), 1 bow, 3 potion types, 4 spells and at least 6 shouts.
Different people = different gameplay, get over it. If a mod like this would exist then i wouldn't need to keep my shouts in my favorites menu and it would be easier to scroll through.
You either play on the console or just can't seem how badly optimized the UI is for the PC.
