For games in public spaces (such as your LGS) where knowing what's yours can be important, I find these useful:

They are small enough to fit on Armada bases, so I just stick one to the bottom of each base (especially squadrons). That was in public games, when the fighters get all mixed up, I can recover my figures when all is said and done. Particularly helpful for same faction and team fights.
Plenty of them per pack to be able to pick a color and stick with it. I prefer red ![]()
And they're cheap.
