I've let this issue slide for the moment. I tried entering the name of my template, "Manuscript" in the blank under document templates and nothing happened. I also tried entering "Own Templates/Manuscript" and nothing happen. From the favored use of the term "directory" and things like forward slashes ( / ) and cryptic words in courier-type font styles, I gather that this is more part of a Windows world in general discussions than us plug-and-play Apple types get: linuxes, unixes, and pythons notwithstanding.
Anyway when I see things like .xml (given what Google says it is), and the dreaded .../Library/... I run away in terror as fast as I can hoping not to have turned my computer into a bubbling mass headed towards the center of the Earth by some errant squiggle on my Magic Trackpad. And anyway, its the least of my concerns now. Given its only a minor irritant for me, I might never worry about it again.
Thanks for your suggestions, someday I might be brave enough to further explore them. Or someone might take up your directions and post the results in the future.
