Cool. I really like it. One thing that I stumbled upon was that, when I was playing with negative numbers on slide 6 I would have expected the x-axis to stay at zero and the line to dip below it.

But I am not really sure how to achive this for the secondary y-axix (I was playing with the percentages and simulating negative growth).

Good spot, it does look like a bug when you are using 1 axis. I'll roll a fix in the next release today. Thanks for the feedback.

Earlier quoted context omitted.

The concept that's MAGICAL in Reveal.js is vertical slides. e.g. https://revealjs.com/#/2/1 You just make one slide deck with lightweight high-abstraction slides and depending on the audience you just... hit the down arrow. bam. now you're inside the tech slides. no nerdy tech guys? sweet, don't hit down on slide 3. Instead you're with the marketing guys, so hit down on slide 5. Anyway - looks like you got rid of tha…

That's a great point. I went down the state slide route in order to handle a similar type of use-case, but I'll look into this and see if we can incorporate that somehow. It seems like a really elegant way to implement some state slide use cases. And thanks for the heads-up on this!

Could the hidden state slides "just" react to a down arrow press as well as to the click? But then they probably would have to have an order somehow?

Just my two cents.

Hi, I'm the creator of Bento. Just wanted to share a bit more about how I created it beyond what's in Github. The file contains more or less two sections. There is a plain block of JSON near the top of the file which is the slide data. You can read, grep, or point a harness at it. The app itself is in a base64 blob that loads through a small shim which deflates in the browser with DecompressionStream, which keeps the…

Very cool! FYI I was able to cause all sorts of hell by pinch zooming on mobile safari. This seemed to throw off the click and drag select box and on one occasion crashed the page entirely.

Let me reproduce it on iOS and push out a fix shortly. Thanks for the heads up.

Hey, I just wanted to say thank you for writing this -- I couldn't find a way of contacting you directly in the repo, so I'll just have to bury this here! I really appreciate the work that went into this, and the design.

Thanks for the kind words. I'll put some contact details in my Github profile.

Technically yes, and the order is just dependent on the chain of the keypress event triggering slide changes. Will investigate the best way to do this.

How do we UPDATE the underlying engine once it gets new features? Since this is a self contained HTML file I am not sure how this works. Editing multiple things at once (select via CTRL) needs some more options (like text centering).

Bento has auto-update baked in. It checks for signed updates in a manifest, downloads it, rewrite the file structure with the new and reloads with the new file.

Awesome. I've been trying to promote this kind of Single-File Web Apps as a concept - feel free to add this to the proposed Wikipedia page: https://en.wikipedia.org/wiki/Draft:Single_File_Web_Apps

Can you create a list on github with known single-file web apps? Wikipedia is not a good place to promote ideas. It is a place where ideas in practice are documented. Github is a good place to promote stuff.

i just launched iamsingle.app to be a directory for sfwas :)
