Sometimes the video on the media player will stop loading or just flat out crash, forcing me to turn the media player on and off.
For some setups, this is fine, but there are many situations where the projector is very far away. Getting to it is a hassle.
An additional way of refreshing the video would be nice, such as a refresh button.
You could place the button somewhere in the media panel (same place where you find volume or video queue).
