Switchblade is an application switcher with a twist; it learns.
As you use Switchblade, it develops a list of your most popular and recently used applications and provides this information in a handy system-wide menu for instant access.
Switchblade gives you complete control over which applications appear in the menu, allowing you to designate applications as favorites, permanently hide others, and dynamically show and hide applications based on their Dock presence or other criteria.
