The following is just an idea of how to improve the functionality of the "presentation remote" feature:

When using the connect app on an Android device as a presentation remote it would be nice if one could add a timer to the screen (probably above the "left" and "right" touch areas).
That means setting a timer to a certain number of minutes and seconds and have that count down towards zero.
After reaching zero it should continue counting the seconds but maybe add a minus or change the color of the time passed to red.
The timer could start with white numbers, change to yellow at e. g. 5 minutes to go and change to orange when only two minutes are left. At these moments the display could also flash or blink to draw attention to the time running out.
