I originally had it that way, but I found that there was too much scrolling around and it was not intuitive.
It does need some work on button placement though. For example, if you accidentally change channels, you can only find the 'previous channel' button on the keypad page. I added a temporary 'prev' button on the listings but I still find myself looking for the previous button. So maybe a frequently used button bar or something.
One tip though, you can disable sending commands to the DVR with the 'disable' button on the info page.
INHO, there seemed to be too many repeat functions on the two screens, that is why I mentioned it....But if you cut out the repeat buttons on the 2 tabs, you could make the buttons bigger (or additional functions) which would help with some of us with bigger fingers or just crappy touch screen dexterity. (I love/hate my X Droid touchscreen due to speed of input compared to a keyboard)
