Hi. I spent quite a bit of time making a PDB file for X-10 (Home Automation, requires IR453 module), and decided to share it. It is available at:

[Link: frii.com]

It supports 1, 2, or 3 line labels for each of the 16 device buttons, using a construction set approach. It might be worth a look even if you don't have X-10, as I haven't seen any other PDB's take this approach.
