One interesting usecase is that you can run a tauri app without any webview windows just as a system tray icon and only spawn a webview window when necessary.

This kind of makes it way more lightweight but only in some situations (obv. heavily depending on the functionality of the app).

Would this be for a service style app that happens to have a UI when you need to configure it? If so that's an... interesting idea, but considering the UI is less important I'd probably mind it less (as someone who is not a fan of Electron apps).

I built a syncing tool that needed to run in the background with a simple UI to control it.

I used tauri so I could easily make that cross-platform toolbar app.

Some menu items spawn a webview (things like settings), everything else is in Rust.
