We want to make sure it's not being written in Electron
At least for me, the story quite simply ends there. No, it's not the GUI toolkit I wish I had, but, if the goal is to develop for the 21st century, then I think that being accessible is the ethical choice. And, given the current tech landscape, that goal is satisfied by three options: Electron, developing three different native desktop GUIs, or deciding not to support less popular platforms.
