I would like to see a Select Current Handler command. Given that Go to Previous/Next Handler is already implemented, that should require only a bit more effort. This would support Copy/Cut of a handler, a not infrequent action.
It would also be lovely, but a much bigger project, to implement “expand selection one scope upward”, a command found in some IDEs and IDE-like editors. For instance, with the lines in a conditional selected, the command would extend the selection in both directions to encompass the
end. Doing it again would go up another level, eventually to the encompass the entire handler, and even a script object that contains the handler.
