I held a presentation at work using excalidraw slideshow. Some things amazed me. First off, I did not have to make any kind of prioritizing or editing decisions while making my first draft. Secondly, deciding upon the slides and the order was very natural and is done in a flick of the wrist or thirty in my case. Finally, ending on the full canvas, it was so easy for the audience to interact with the presentation, people coming up to point at which part they wanted to talk more about.

Right now I'm at a conference where presentations will run from the session chair's computer. I don't dare use anything other than power point, but I would love a future where I could confidently run an excalidraw type of presentation in this setting as well...
