I really wish it was integrated into the game better. Like having an npc say 'I ought to give you something for helping me out earlier, would you like this dagger or a crate full of potions' or whatever would be more immersive. I really don't like the MMO-style reward pop-ups.
I already give my feedback about this but yes... totally agree with this.
If they want to give us choices add them in a dialog, eventually with a tooltip that appear when you highlight the item names / descriptions in the dialog... it would be A LOT better than those awfull mmo-style windows and the player would have the same informations...
