ability to pin/lock tabs to not accidental close them

[Chad90b]

a feature to pin (or lock) tabs so you dont accidentally purge them with ctrl+w / middle-click / close other pages / close pages to left/right etc.

some sort of cute lock symbol on the protected tab is obligatory

forcing protected tabs to some sort of default position like browsers do is not wanted. browsers force all pinned tabs to the left and that is very annoying.

Though seeing how some people would expect and prefer that behaviour it should be an option.
