Record demo video

After #1001

At this point it's probably worth taking a breather and running over the app in general and cleaning it up to record a decent demo before diving into the last productionization steps below:

• Fix a huge amount of bugs within the app itself
• Do a push on QueryBuilder, Drag/Drop, Clipboard, Dock
• Bugfixes around opening multiple windows
• App level fixes: lists, people
• Some performance fixes for the demo
• Some last app demo improvements (moving data around ideally)
• Attempt a hacky demo video
