Suggestion for project fair

I was thinking...

For the project fair (not the slide presentation), when people come to your table, you could do a live demo of:

• how to edit a file in the UI
• how to replace a file (with one from your pc)
• how to view a diff
• how to revert the change

These are just ideas, feel free to just do what you're comfortable with, or close this issue if you have other plans.
