There is something I don’t understand, though.
The website says, “Download for macOS. Windows version coming soon!”. Why? The entire application is a website with an Electron wrapper. I thought Electron’s purpose was to allow web developers to seemingly build cross-platform (hybrid) web/desktop applications using web technologies. I do not understand why this is macOS only right now, especially considering that anyone can access the web application using this link [1].
There are still cross-platform differences even when you use Electron. Heck, there's differences when you just use Chrome as a normal browser. For example, the delta value of a mousewheel scroll event when the user is holding down their meta key (ctrl or cmd) can be very different between Windows and OSX depending on the input device. There are differences between Windows Display Scaling for high pixel density screens on Windows and the scaling on OSX for Retina devices. And so on. They're problems right on the edge of app development so they're hard to find and hard to fix. You should not just write an app using browser tech and assume the browser will make it exactly the same on every OS. Until you've tested and debugged on a platform you shouldn't say you support it.
Right now I am using the minimal three js web editor. Mostly for gltf export of hand drawn models.
