I don't think the device left/right buttons are a good solution for suppressing the device macros on large setups. If you have four or five devices, no big deal, but I have eleven, and it's not reasonable to expect guests (or even myself!) to remember what order they're in so as to avoid scrolling through page after page of devices. I had the device left/right buttons enabled when I first started programming my 3000, but I found I was never using them because it took too long to get to the device I wanted. Now I've disabled them and put "home" and "help" buttons where they used to be.

To me it doesn't seem unreasonable to want to configure the whole user interface, including the start page. I find it a little odd that the 3000 has a concept of a "home" device but doesn't appear to treat it any differently than other devices, apart from there being a built-in action to jump to it.
