Do you have so many programs installed that the default Bevy view is a bit overwhelming? Bevy lets you customize it in several ways. For starters, you can exclude a particular program from the display, although you have to perform this action separately for each program; there's no way to exclude apps en masse. (There's also no way to exclude entire folders; for example, I'd like to keep anything in /Applications/Games from showing up up in Bevy.) Convenient buttons at the top of the Bevy display let you quickly switch the view to show excluded programs, all programs, or just running programs.
Alternatively, you can filter the display by holding down a letter on your keyboard to highlight those programs whose names include that letter capitalized. In other words, holding down the T key will show TextEdit, Time Machine, and Twitterrific, but also iTunes and QuickTime.
You can also create folders of applications and point Bevy to them; each folder of applications is presented in a separate section in Bevy's display. Unfortunately, Bevy doesn't support aliases to applications, so you can't create a folder containing aliases to your favorite programs and assign that folder within Bevy.
Don't recognize an icon? Bevy displays the name of each item as you mouse over it; hold the mouse cursor over an icon and after a second or so, you'll see the full path to the program. Unfortunately, you can't Command-click on an icon to reveal that program in the Finder, as you can with icons in the Dock.
Dragging a document into Bevy's display highlights those programs that can open the file.
