Tried the LauncherPro Plus (paid unlock of the free version). Caused some weirdness after installed. I would advise folks to clear off their home screens before loading the LP+. It zaps whatever was there anyway, but in fact, the original screens aren't gone. They re-appear if you uninstall LP+.
When LP+ is added, some of the widgets don't work right or are extremely slow - for example the Moto widget "Contact quick tasks", which I use for all family members. I'd guess the fact there were a bunch of these on my original home screens and then another bunch added to the LP+ home screens caused conflicts.
Ultimately, I uninstalled LP+ (sadly, I have to add). Loved the 15-icon revolving dock and all the customization that was possible, including the number of home screens. Might try again later, but if I do, it will be with clean home screens to start. Hopefully, this will make a difference. Otherwise, though, the app functioned very well.
Also, the app Extended Controls has been absolutely terrific! I built two 1x4 strips with all sorts of handy customizations and used the colorful Moto widgets for the basics: Bluetooth, WiFi, GPS and Airplane mode. Now using a whole screen as a "control panel."
If anyone finds a screenshot app, please post. There are several for the BlackBerries, but so far as I can see, none for the DX.
