Hello woodall, you can add a file by clicking the plus button in the bottom left of the screen. If that button doesn't appear for you, then that's a whole other issue. Please let me know. Similarly, the minus button removes files. Double-clicking a filename lets you rename it. Edit: Just noticed how unintuitive the position of the +/- buttons are. I'll see what I can do for Plunker 2.0
