Tab List - allow delete

[Malarki]

Working within locked folders incidentally creates many tabs that aren't needed later. XY will reduce all the tab sizes but reaches a limit. With my Config settings, the oldest ones get pushed off the right side of list pane and in some cases can't be seen again without deleting newer tabs.

Currently the "List Tabs" button only permits navigating to open tabs - but that doesn't bring the tab into view if it's been pushed out of sight.

--> I suggest adding the ability to close tabs from the "List Tabs" list. AND / OR bringing a pushed-off tab into view if accessed from that list.

[Unless the upcoming new XY will have a "scrolling tabs" model with "<<" and ">>" buttons.]
