I should mention the last features of the Omnitrix, like the Omni-Enhancement Feature which requires both equires Upgrade and Shock Rock to Unlock. 

This feature gifts the transformations with armor that amplifies their abilities. Available Omni-Enhancements include Shocker Armors which are inspired by Shock Rock, the Hi-Tech Omni-Kix Armors, and the Omni-Naut Armors which grants the ability to survive in space on top of being Hi-Tech.

The Evolution Feature works by placing the DNA of the selected alien in a simulated scenario, subjecting it to the worst-possible threat over millions of theoretical years to "force" evolution in the genetic code to the species' Ultimate Evolved Form. The resultant evolutionary adaptations to this fictional threat scenario are then modified into the existing DNA of the selected alien, thus evolving it into the New Ultimate Form. This "Survival of the Fittest" method of simulated evolution ensures that the Ultimate Forms are much more combat-oriented than their normal forms, and allows them to survive even the harshest conditions. Almost any DNA can be put through the evolution process. 

And Master Control allows the user to transform and/or access any other function/feature with a simple thought, neglecting the use of the dial. The limiter will also be disabled, allowing the user to stay transformed indefinitely.
