Play/Pause action is broken
The space bar is given as shortcut key, but most of the time it doesn't play/pause the video and it either scrolls the page or takes in/out of the fullscreen. Clicking on video window to play/pause doesn't work like other video players, and have to use the actual play/pause button on downleft corner instead. Using 'K' shortcut key instead is really not a good alternative, as the letter 'K' doesn't feel connected to the Play/Pause action in any ways and could have been 'P' instead.
This is quite annoying and should be improved.
