Oatmeal is a yummy way to increase supply.
Mommy Necklaces give nursing babies something to focus on so they don't whip their head around as much. *ouch*
If you don't want to spend a bunch of money on nursing tanks for under your clothes, you can use a BeBand that's the same color as your nursing bra and pull it all the way up. You can't tell the difference!
Big T-shirts double as nursing covers in a pinch, just pull the bottom of the shirt over your baby's head. This is a great tip to use with the one above so you aren't showing any skin.
If you have large breasts like I do, try different angles until you get baby to be able to latch without their nose being buried in your breast. This frees a hand so you can eat or type.
No-handed BFing without a Boppy - sit cross-legged with baby's head on one leg and baby's butt in your lap, that way you don't have to use an arm to support baby's head. If you're in a chair, cross your legs like a man (ankle of one leg over the knee of the other) and do the same thing. It might hurt your back a little more, but it helps you be able to get stuff done on the computer.
