Ok, so I’ve seen or been asked the following question A LOT of times since the Annotate Meet extension came out, and to be honest, ever before that.

How Can I Annotate Or See Students When I’m Presenting Google Slides Full Screen?????

Long story short, it doesn’t look like you can. So here’s my solution.

DON’T PRESENT SLIDES IN FULL SCREEN!

Then what do you do? This. I’ve created a bookmarklet called No Pane.
1. Click and Drag this link to your bookmarks bar.

2. Open any Google Slides presentation.
3. Click the No Pane bookmarklet and watch your Side Pane Disappear!!!
4. For more visual clarity, click VIEW and turn off the Ruler and the Speaker Notes.
