Better way to change screens

[TiVoHomeUser]

Missing feature

Screens only change in one direction on screen press. I would like to press:

• Middle right move to the next screen
• Middle left move to previous screen
• Bottom 1/4 goto screen 0
• Top 1/4 change 12/24 time format (existing in current code)

Justification

Better user interaction

Workarounds

in loop() replace

    screen = (screen + 1) % screenCount;

with

    if (p.y < top) {
        IS_STYLE_12HR = !IS_STYLE_12HR;
    } else if (p.y > bottom) {    // Go to page 0
        screen = 0;
    } else if (p.x > middle) {    // Previous page
        if (screen == 0) {          // Note type uint16_t is unsigned
            screen = screenCount; // Last screen is max -1
        }
        screen--;
    } else {                      // Next page
        screen = (screen + 1) % screenCount;
    }

Should be else if (p.x > middle)
