update:
woohoo, got everything exactly how i want it:
i noticed that after you paste welcomecenter's GUID, you can no longer edit it via configurator... so what i did was close chome, paste settings' GUID onto the custom panel (make sure to take note of the one that's in there before you paste!), open chome then close it again (the custom panel wil be invisible again), then open configurator and you should be able to edit it again. when you're done, just put back welcomecenter's GUID and you should be good to go... (makes me wonder if pasting settings' GUID to one of the built-in chome panels will allow you to edit it.... *ponder*)
