Discussion: Add ability to close tabs via double-click

MissyQ, I'm generally supportive of providing options to help people work the way they want. This is an exception. Double-click has a very specific meaning as a core part of the UX: Double-Click (except for a few violators) means perform the default action. Generally (not always, but should be for consistency) right-clicking  provides the list of actions/verbs, with the default action bolded. Double-click performs that. This action is NEVER to close something. You double-click to open, launch, etc. 

Please do NOT make double-click a close action ever, in any application. This will just lead to a splintered user experience and hurt Windows, Edge, all applications that work with a mouse, etc.

I don't mind allowing some non-standard combination, like pressing both left and right mouse buttons at the same time or a double-right-click, because (as far as I know) those do not have an existing standardized meaning, but not repurpose a standard action (double click the main mouse button) to an entirely different function.
