Is there a possibility to create a view only user, so he couldn't make changes, create tickets, tamper with settings and etc?

If you press "alt" it handles it as a typing event, so when you alt+tab out of the browser, it's as if you were typing. I believe a typing event should happen when an actual character is typed.

The bot won't forward the message to the user when privacy settings like:

No error handlers are registered, logging exception.
