Are there any plans to make this a desktop app. I despise graphical editors in a browser

I've been considering it. If you'd find a desktop app useful, please do open an issue on GitHub: that way I can gauge the demand a little better, which will help me to prioritise what to work on next!

Please ignore Electron requests and consider the PWA approach.

Nice app by the way.

Diagrams.net is using electron for the desktop app, it works really well (and is fast despite what people often beieve of electron)

The problems with Electron isn't speed, rather memory bloat and multiple Chrome copies scattered around the filesystem.

The path forward are PWAs and the ability to use them in any browser.

Otherwise don't cry that Web has turned into ChromeOS, when everyone and their dog is shipping Chrome alongside their application.

An electron wrapper?

It's written in javascript, you entitled twerp! The author has created this beautiful tool for free in his/her spare time.

It is written in JavaScript, so you will need a browser of some kind (Electron is basically a browser), unless it gets re-written in a different language.
