// iterated through, and therefore the newest item you just added and want
// to edit.
//
// I got substantially far along the way to making this quick and dirty hack
// work before I thought it would be a lot cleaner to have the
// AddControlParameterCommand itself launch the dialog and allow the user to
// edit the parameters before ever adding it to the list at all. That would
// be a lot cleaner, but it would also require going against the flow of how
// this logic always worked, so it would require a lot more thought to
// achieve the same end result that way. Instead, I just used this hack
// overloaded slotUpdate() to tell it when a new controller was added, so we
// could grab it here and launch the dialog on the generic blah we just added
// to the list right before this slot got called with the optional bool set
// true.
//
// (so much for verbose comments being helpful... I wrote that not too long
// ago, and reading it now, I have NO fscking idea what I was talking about)
