I just sent someone on the list here a copy of "CoCoTop", which I sold for a couple years wat back when. It's an OS-9 file/utility shell very much as you guys are describing. It was intended for those unfamiliar with OS-9, and would do all normal file manipulations and one could launch a program, which would auto start in another window. I can't remember the author's name right off... but I had rights to it. If someone gets a copy and diassembles, then uses that as the basis for something new I don't mind -- as long as it's made PD and/or distributed at a reasonable copy/shipping/handling fee.
