Ordering of command and options within command.

[hmble2]

Both of below:
@ShellMethod(key = {"attach-task", "at"}, prefix = "-", value = "Attach file to task.")
@ShellMethod(key = {"at", "attach-task"}, prefix = "-", value = "Attach file to task.")

displays:
at, attach-task: Attach file to task.

At times I prefer to keep the ordering that I provide. Could we have a flag to suppress natural ordering?

Same goes about order in which commands appear on console (vs definition order in java file), I would prefer them to appear in the order they defined in Java file.

This is something what had been asked few times like in #636. In light of that it's time we do something about it.
