Understanding Startupizer
Startupizer extends functionality provided by login items in your account settings in Mac OS X System Preferences. The main benefits are provided by various types of criteria that can be applied to each item (an application or a document). Criteria allows you to precicely define conditions that must be met in order for an item to be executed at a specific time. This can dramatically reduce startup time and thus make you more productive.
Another benefit is the possibility of executing items after awaking from sleep, not only after logging in to your Mac OS X account. This makes Startupizer more versatile as it can suit broader group of users - those that regularly shutdown their computers and those that put it to sleep for extended periods of time. Startupizer also allows reordering items which affects the order in which the items are executed.
In order to be able to handle conditional startup, Startupizer must get control over login items. This means, it moves these items from your account login items list in Mac OS X System Preferences to it's own internal database. Only items in Startupizer's database can use advanced options! Once items are moved to Startupizer's database, Startapizer takes over the task of executing them when appropriate. To allow execution at login time, Startupizer adds itself to System Preferences login items list. Actually, until you start applying startup criteria, all your login items are still executed, exactly like they were before! Note that you can restore items to system list at any time!
