Show a Play/Pause addon is an option available exclusively for Desktop projects because the touchscreen devices can't visually show on screen user's previews to the interaction moves, such as Hover, for example. Therefore, the present article explains how to set up the option Show only for desktop's projects since the option Show is not available for multidevice and mobile projects, because the button is always visible, when the option Full screen is unchecked.
If you set the drop-down parameter Show on the General submenu with the option Always, the Play/Pause button will be displayed all the time –within the time you had previously set–, if the mouse pointer is in movement as well as if it is not.
Show only on mousemove
If you choose the option On mousemove on the drop-down menu itself, the Play/Pause button will only be displayed when the mouse pointer is moving. As soon as the cursor stops, it will disappear and will appear again when it detects movement again.
