I am using opera on a school laptop and sometimes my friends like to peek into it when I go to talk to the professor. I would like to add an option where the user can let the full opera window to turn into a password screen after a time of inactivity specified by the user. or when the user clicks on a hotkey. and showing the password screen when opening up opera. This is just so that I won't have to always open incognito mode where I have to constantly log into my accounts. Plus it adds a level of privacy which is very much needed as a personal browser. I use this on my main computer too so yes I would definitely want to have another layer of security.
