This idea is basically just for the command panel. If we have a classic look, why not a Neon/Toyota look. I was thinking that the panel could be the psycic panel, the dcanner panel or (what I would prefer), the panel with heaps of buttons.
Another bit is getting back the old Classic monitor block, so that we have the ability to switch dimensions without leaving the console (the wall one is annoying to use).
EDIT: Maybe, instead of re-adding the old classic monitor, the TARDIS Panel could get a command that opens the GUI for planet selection.
