Don't delete it without uninstalling it from HackMaster first. Just set all six sub-apps to the same thing in the control panel. If AppHack detects no ambiguity, it'll go ahead and launch the app straight off. Not if you use it right. A poorly-written Hack can seriously screw up your system, but if everyone plays by the rules it's as safe as installing a system update patch from Palm.
Hacks have to cooperate for multiple ones to coexist on the same trap.
The order in which the Hacks are installed makes a big difference. If you find that Hack A is preventing Hack B from working, install Hack A and then Hack B on top of it, so B is listed before A in the HackMaster list. If you're a relatively experienced PalmPilot programmer, you too can write system extensions under the HackMaster model. Have a look at the HackMaster API and have fun. However, this will prevent the automatic reinstallation of your Hacks on a reset, and will delete the Hack registry.
