For those interested in desktop app.
Here is initial draft version built with neutralino
https://3d.hrg.hr/jscad/desktop/draft1/
the desktop app is just wrapped jscad.app there is currently no specific customizations in it to enhance desktop experience.
it should work well if your OS web view is chrome (I did not implement FS access through neuralino yet)
to run it, download both: executable for your OS, and resources.neu, put them in the sam dir and run
Feedback for different OS is welcome, I only have windows available to test currently.
