If you've built a Windows application on Electron...
For anyone who hasn't had the dubious pleasure ... remember about 20 years ago when they rolled out Java apps and lied that they could match a native application C++ application in terms of UI quality and speed? Well, it's like that. Only worse. Much, much worse.
The Electron version of Skype (for example) is such a giant leap backwards that I strongly suspect it was built by someone attempting to graphically illustrate why lowest common denominator cross-platform works no better today than it did when they rolled out UCSD Pascal in 1978.
