Something I can't stand about the videos on this site... the spacebar doesn't pause the video. And not only that, the play button goes away on the video after the mouse doesn't move for a few seconds, so the only way to pause the video is to first move the mouse, then click the pause button. ugh.
I love to be able to easily pause video and press the <-- arrow key to rewind playback a few seconds, to rewatch things quickly and easily. YouTube lets you do that, but not here. I guess I'm so used to being able to do it on YouTube that I'm a little spoiled. Well that, and I'm a web developer, so I know that the designers of this video streaming software should know better.
First-world problems.
