Duh Button Launcher Plus (DBLP) is an application that will let you switch applications with the ease of your device's hard buttons, without exiting the current application. After installing DBLP, you can map up to 20 applications on your Palm, memory card, or DA�s (Desk Accessories) to each of the four hard buttons (datebook, contacts, tasks, notepad).* With several customizable options, DBLP is not only a program launcher, but a powerful DA launcher for Desktop Accessories (DAs). DAs are small applications made to simulate multi-tasking to the PalmOS, in that they are able to be run without exiting the current application. The author has included several DAs in the download for DBLP (included in the zip. NOTE: these DAs improve functionality, but are NOT required for the application to function on your device. Please see the included README for full operation instructions.).
