Close chrlauncher after successful update

[tooomm]

After the update is correctly downloaded and installed, the browser gets started... but the chrlauncher window stays visible and is not closed.

I would like a lot to see an option to auto-close the app after it's done searching/installing an update. Just like it vanishes immediately once no update is found.
Probably even enabled on default?

For me it vanishes into the tray, but I would prefer a full close too. Just like when there is no update, then it closes itself.

Mostly related, I'd like to be able to just disable closing to tray.
