Being able to lock the extension quickly is beneficial to security and privacy, such as in a busy workplace or public space. Currently we need to click into navigation and find the lock function in the menu, which takes extra time and clicks.

I propose having a lock icon/button on the top of the extension UI, near the search bar or "Add new item" button, for easy and fast extension locking when needed.

Bonus points if we can set keyboard shortcuts but not sure how feasible that is.
