I discovered not to put any spaces in a psave file name. It truncates the file name and you may have ten or twenty psaves all overwriting the original. That wastes a lot of work.
iirc, the default file name is something like cmeye.txt but I'm not sure.
Additionally, every time you use cmeye after you do a default psave, you are returned to the psaved position even if you change terrains.
