This is a little off topic but: I am watching your video and just paused it to tell you you can turn of the sound affects of selecting bricks in the preferences. You can also use LDD Extended to have more pieces (plus each piece is only displayed once) and color them with the paint bucket. Apologies if you already knew this information.
Edit: you can also just go to the "file" tab and click "Export BOM" and it will make a document (excel spreadsheet?) with just the pieces. This is how I made the parts list.
