Changing my old Pronto RU990 to the TSU9400 with its more numerous hard buttons allowed me remove the tabs on each page, and finally make full use of the screen. In this I've made sure all my components' functions fit on 1 page, (with a seperate page for each zone on my AV Amplifier), whilst keeping the button sizes larger and more attractive than I've used before. I've kept the system area as small as is practical.
I've also made use of Pronto scripts to cater for short/long presses of the power button (on/off) and page scrolling of the Sky and Freeview TV guides using the rotary wheel. Every device is accessible from the home page, and I've PIN protected power to the projector (The PIN is 5555 on this version). You'll find every IR code you can think of for each of the devices, including the commands used in all 4 zones for the Denon AV amplifier. Hope it's useful.
