Oh, you know I totally overlooked that. Let me post my suggestion for that here as well as edit the OP:
The way I can see this being implemented goes as such:
All logged items, in the order they appear in the log, are placed at the bottom of your screen as if you had every single item you've currently logged in the game, except they are 50% more transparent than if you had them. Clicking on an item will add one to your item count, and add 50% opaque-ness to show you've acquired the item. Right clicking will take one away.
On the very left side of the screen, there will be a picture of each drone (they're small enough to fit there) that are also all 50% transparent. You acquire drones the same way as items. You can add and remove drones as you wish. This could also possibly be implemented to other difficulty modes to show how many drones you have and of what type!
