"Repeat Last Command" menu entry (assignable to hot-key) and command multiplier like Boxer.
Currently, SE has only "Execute Last Macro" which is a misnomer as it is really "Execute Last Recorded Macro."
Many recorded macros are reliant on Ctrl-F12 to repeat them. If saved, there is no efficient way to reuse it. Further, Boxer's implementation of Repeat Last Command & Command Multiplier is NOT restricted to macros. It can be used for any command.
