My common work flow is something like resmoke --suite=foo --continueOnFailure -j10, see which tests fail, then copy-paste them to resmoke --executor=foo LIST_OF_TESTS. It would be nice if I didn't have to change --suite to --executor since resmoke can easily figure out what I mean.

I don't think the distinction between --suite and --executor is buying us anything since they basically mean the same thing and --suite currently errors if any tests are specified and --executor errors if no tests are specified. It seems like they could just be combined.
