Locked tabs functionality

[raduricoh]

Description

Hi,

Is there any possibility to consider implementing some sort of "lock" mechanism for tabs?

• The page URL should not be allowed to change; or maybe allow only subdomains, subpages etc.
  • If there is a URL change, maybe there can be opened a new (child) tab for this new URL
• Also prevent simple tab closing (inadvertent or not) - e.g. by throwing a pop-up for closing confirmation

Thank you!
