enable selector as cli overriding option - feature request

[muralikodali]

I think one of the strong use cases for this program is selecting an option for opening files.

we naturally set a default application for the file types. for some file types, there will be more than one program. It provides more flexibility to call selector option (which can be overriding the option set in configuration file, i.e: enable_selector=false).

I request you to provide this option, to selectively call (with this overriding option) this application from other programs.
