Syncthing panic not shown on GUI

[Xeenych]

I have ST running on my laptop. I was trying to sync for a whole day unsuccessfuly. Then I looked at console window and saw panic messages due to corrupt database.
So, what is happening.

ST starts -> tries to sync -> panic -> ST restarts -> tries to sync -> panic - and so on.

There is no indication on GUI, but there should be!

If ST runs as a service without any console windows, the user cannot find if the panic happens

That's not possible for persistent panics: A panic brings the entire program down, i.e. there is no web UI in which to display the panic. It should however be obvious that something is wrong when trying to open the UI, because it's either not there or keeps dis- and reappearing.
For one off panics, i.e. if it doesn't occur anymore thus the UI can run, it would indeed make sense to detect the previous panics and show an indication in the web UI.

In my case panic occured every ~5-10 min. So, every 5-10 minutes I saw a disconenct in web-interface and then immediate reconnect. It looked as a normal behaviour.
So detecting prevoous panics would be very helpful
