I'm working on it alone, which is possible thanks to Electron and Chromium projects which are abstracting away the difficult tasks. BTW, the widget toolkit used by Boxy SVG is open sourced and can be used by other projects. You can try it out on https://xel-toolkit.org https://xel-toolkit.org. In near future I'm planning to improve it by adding Windows 10 theme and full support for color schemes and dark mode.
