Cool! I'm still testing them, but they look good (Throwback14 loads blazing fast). My favorite is Throwback14MP.tpl. Overall speaking, you did a great job (it looks like a finished/completed project), congratulations! 
Thanks ever so much! I wouldn't have done so well had it not been for the stout/clear and helpful briefing that you gave me (also kudos to Rejetto for a do-in-scope briefing). And, yes, it is intended as the series finale, at least for now. Sharing all that I could, was good advice.
...removed my XHR login...
I did. For the phones, I put a note to use a browser that is compatible. It is a new development, since mobile browsers with basic-auth capacity have only recently become available, via firefox.

MP was always the favorite. This is why Throwback14dphoto behavior and default workload is very similar to MP. Because of the new state-of-the-art color css unicode icons, today I tested large folder support again. I got 234,691 files on a single page during the test (of a disk with exactly that many files). It went a minute faster. And I did it from a cheap TracFone on metered mobile data. So, the newest did have large folders support. Test was done with the photo version; and, this time, minus the bill. Perhaps, the #14 photo version is now eligible as a favorite.
...14 loads blazing fast...
Throwback was always dual purpose. #1, serviceably fast. #2, a practical message to the developers: never less than this.
...finished...
Indeed, the classic/interactive interface is stuffed full. Although it surely will arise again, the next step should have its own name and its own thread.
