This system file includes two setups (livingroom and home theatre). Most of the device logos have jumps attached. Has a basic "tab" setup for quick TV channel selection. 2nd hard button = jump back to main screen. 3rd button = go to 2nd or 3rd device page. "f" key = backlight. Few BMPs, no discrete codes. Main focus has been on usability - what to combine on one screen - how to operate with the least amount of screen changes - no use of side buttons. It took me about a month to puzzle this together. Still a work in process but everything works.
