5. If you're going to leave it that way, then at least some of the confusion could be eliminated by making the disabling happen when closing Options, rather than the next time that iPT launches. Also, a message box warning the user of the elements that will be disabled and giving them the option to not go ahead with it (just like the warning when enabling "Alphablend on background" when the devices that don't support it).
6. On the "Icon Settings"/"Edit Icons" page, changing the icon # doesn't update any of the information on the page on my device. Is it supposed to? That would be really nice, if possible, so that we can know what icon we're editing after we've changed the icon number.
Also, I've re-done the bubbles in 96x96 and they look a whole
lot better at the larger icon sizes, probably because one re-scaling is eliminated. I should've just made them in 96x96 to begin with. Oh well. Here they are. See the attached zip to download all of them (and with correct filenames).
EDIT: I fixed the shadowing on the transparent versions and tweaked the highlighting to make them more bubble-like. FYI, they look here like they're all white, but they aren't. They'll look as they should in iPT.
