Just opening so I don't forget, this should wait for v3

As we're here, perhaps we can also get rid of shared_app_impl!? Rust analyzer basically don't work when writing things inside of it

Also maybe WebviewWindow and WebviewWindowBuilder? We can make a trait Webview and Window and implement things there so we don't have to duplicate things every time we add something in it

If you guys think it's a good idea, I'll put it on 3.0 so at least we don't permanently forget about it

Yeah, I have been wanting to do that for quite some time but don't have the time just yet. This would need to have tauri::prelude module with it.

run_on_main_thread_blocking would be a name that matches with our dialog plugin APIs
