For fun of course - Rust is a much more interesting language than JavaScript. Up until recently I cared much about Joplin being faster and using less memory but this became less of a concern since I've upgraded my PC.

This is irrelevant as Electron is only used for the desktop version. Mobile uses react-native which is a completely unrelated technology. CLI is based on something else, not sure what exactly but it's neither Electron nor RN.

And to be clear -- no one is doing anything on this.
