Could you please clarify which thing? Also if you are interested in how something on it is done, all the code is here https://github.com/DustinBrett/daedalOS

Ah yes, I mean that graph where each node is a note that can be connected to other notes, you know? Like a mind map?

Do I have such an app? Sounds cool anyway. Do you have examples or links?

Oh sorry, HN usability played with our hearts :D

The message was meant to this other dev, quite cool mind map:

And I'm impressed by what you have done there. I even played a bit of DOOM heh.

Your project reminded me a little bit of https://squeak.js.org in the sense of having a full OS like thing in the browser.

Congrats for the achievement!
