We need to add watermarks to any roadmap slides that we show.
Thank you for your idea. There are two options here that currently exist.
In the slide editor, you can add text fields to any slides that need disclaimers
You can add a disclaimer to the footer of your slides. This will show up on the web page for every slide in a presentation. The footer can be set in the notebook customization options -- see attached screenshot.
Given these existing options, we are not likely to add an automatic watermark on views added to slides.
