The Delay Tab allows you to modify the type of Delay, if one is applied.
An Automatic delay will determine the best time to launch the Application according to the state of your Computer. You can modify the Idle percentage values on a per Applicaiton basis, or modify the default from the Options window.
A Manual delay can also be used, by specifying an arbitrary time value to wait before launching the Application. This method is not recommended as it doesn't take into account the state of your Computer.
