Just a quick one for the MIME-type file.
I clicked on a shell script, in this case on http://oss.zonbu.com/ and instead of offering to open it in the text editor, it suggested the appropriate application was `less`, the command line utility for “paging” text. (If you don’t know it, it’s a cousin of “more”).
I’m thinking that the included ‘notepad’ application is probaby more appropriate.
