Yep, well, only supporting IE9+ unfortunately makes this unusable for production websites at this point, as a huge portion of users is shut out.

Small Typo: "A HTML5 client-side solution for generating PDFs". I think it should be "An HTML5 client-side solution for generating PDFs".

Fiercely off topic, but it depends on your pronunciation of "H"

They don't act differently, its just a dyno separate from the web and other processes.

This looks nice! Watching the video I was just wondering if it would be more useful if all code that is executed would be highlighted instead of the 2 colors for conditionals. That way one could identify the actual code path more quickly.

Shows an empty list for me and hangs, can't input anything...

See my comment to _frog: IcoMoon icons look pretty good, even on windows with chrome...

Check out the IcoMoon icons, they don't have the fuzzyness like fontawsome icons for example...

Okay, after starting it for the 3rd time and not maximizing the app I could interact with the gui for a while. But then I clicked on Top-Level-Element Audio and couldn't click anything else anymore afterwards... By the way, trying to resize the window has the same effect like clicking fullscreen: The window area becomes mostly white with some grey rectangles in it. Only fix is to quit...

Sorry about that! I assure you it's not supposed to do that :)

Is your Retina MacBook Pro the 13" model? I wonder if there's an incompatibility with the Intel HD Graphics 4000 GPU. I don't have one for testing, but in the past I've seen quite a few issues related to how Intel's integrated GPUs diverge from the traditional NVIDIA/AMD chips.

Could you look in the Console to see if there's something printed when you run the app and things go wrong? This is getting off-topic for a HN thread, so if you have a moment to look into this, please drop me an email: pauli /at/ lacquer dot fi. Thanks!

Looks quite good, but seems buggy on my retina macbook. First time I started it I couldn't click anything. Second time I started it I tried maximizing, which turned the screen white, had to quite again. Now I'll try for a 3rd time... ;-)
