It's not highly performant, its startup time is a multiple of that of native apps. Nothing is easy about plugins, APIs you expose/maintain define that, not Electron, and those can be good/bad in any system. Electron gives easier access to UI styling, but then again, real "easily" comes from the structure/stability of your UI, otherwise your plugins would break all the time. Also, same as with APIs - e.g, Joplin is Electron, but you can only style on a desktop. Then, of course, there are plenty of Electron apps that you can't style at all and that don't support plugins.

I'm happy for devs' "faster development", but as a user I care about "faster use", which Electron blocks outright
