I know you guys will get the quirks worked out.
For me, working this evening with just the laptop (and not my normal 3 screens) being able to start, pause and stop the sequence is a very big plus.
You guys do good work!
Edit: FYI - if you pause your sequence using the control buttons, you can move the slider to a new location (forward or back) and it will pick up at that point. It won't do it while it is playing, though.
