In the decades-long process of getting my fvwm config JUST RIGHT, my xterm right-click menu now has a "duplicate" command, which opens a new xterm with the same geometry, on the same node, IN THE SAME DIRECTORY. (Directory info aquired via /proc.)

(I expect I'll still be tweaking this when Wayland is but a bad memory and everyone is switching to The New Big Thing.)
