Quickly launch one of six applications simply by holding down a hard button on your palm device. Holding down a hard button, such as Datebook, Contacts, To-Do List, or Notepad will scroll through up to six applications that you mapped to each individual hard button. When you let go of the button, the highlighted application will launch. The great thing about DBL is that you can also assign buttons to applications that are stored on your memory card, especially great if you have little memory and are using the standard Palm OS launcher! DBL also includes some essential functions such as brightness minimum, middle, and maximum, to quickly change the brightness settings on your device, as well as no-nonsense power, and soft reset functions. Best part about DBL, it's free, released as freeware by Supertrucker (Andrew J. Diamond) and Lukas Grundmann! Download and enjoy the benefits of DBL today!!! Update Description:
