Invisible Google Slide Control Bar is a Chrome add-on developed by thumbd12856. This free tool falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. The program allows users to control the visibility of the Google Slide control bar while presenting.

One common annoyance when presenting with Google Slides is that the control bar appears whenever the cursor gets near it. With this add-on, users can now choose when to display or hide the control bar by simply pressing a button. This provides a more seamless and distraction-free presentation experience.

To test out the functionality, users can visit the provided simple test page on Google Slides. The source code for the add-on is also open and available on GitHub for those interested in exploring it further.
