Show Creep HP/Armor/Damage

My main complaint as a new player is the inability to determine how powerful one unit is compared to another.  Damage numbers mean little if I can't see the target's total hp (this is with regards to creeps).  Experience will answer this obviously, but providing the option of numbers would go a long way to making the game more accessable to the numerically inclined.

Toggle Numerical Health Bar

A toggle for keeping health-bars on would also be much appreciated, and as it stand knowing when to use that health-potion effectively or whether or not the Rook can one-shot you with his hammer requires mousing over the bar.
