@leocg you mean like this? yes, but it didn't work. I also couldn't find 'timestamp'
edit ok it worked when I did the change in local state file when opera is closed. it would be really good to be able to change/edit default search engines in opera settings page with using the UI.
edit hope this won't change back when an update comes?
@leocg of course it would, this is just an additional measure if you leave your PC unattended for a while to be safe, or if you're sharing the same account with other people, if situations emerge where you have to provide someone short access to your pc and not having to creep over their shoulder to what they're gonna click and so on..
It could also be used as parental control to limit children accessing certain sites (it's much easier for an average user than configuring restricted access on your modem), a lot of use cases could be derived from this
