I'm currently in the process of designing a new MX-3000 interface. My design features a toolbar which persists across every page with helpful buttons and info. One of these is a "Useful Tools" button which jumps to a page featuring an assortment of buttons that are useful across many different activities, like an aspect ratio button, a sound field button, night/loudness buttons, etc.

For the sake of ease of use, what I'd really like to do with this Useful Tools page is include a button that returns you to whatever page you came from. I'm finding this tricky to implement though, and I'm looking for advice on how (and if) it can be done. I can think of at least one way, but it would be extremely cumbersome to program.

I appreciate any help you guys can give.
