Sounds cool, but Electron is so... buggy. I tried building once and the app was a white blank screen, which was a common problem. If it works alright it uses gobs of memory. Is that something you have found improvements for?
The white app screen was an issue I ran into before as well. The error would frequently mean you had some error in your bundling or configuration which would prevent the frontend page from loading (hence, the white screen). The template doesn't have this issue.
Tauri (https://github.com/tauri-apps/tauri) uses less memory, but relies on a different browser so your app may be inconsistent cross-platform.
