I've used grey utensil holders from Ikea ($1 or $2) in my driver drawer. One for Phillips the other for flat, and long ones behind them. Will take picture later.
I have organized mine into types. Could be better but I have too many to spread them out much more. I have my torx drivers and a bunch more screwdrivers that I don't use in another drawer, haven't figured out what to do with them yet. More in the basement, more in my tool pouch...I have too many.
