If I crate several different categories, each with a different slideshow and then select them in the Module, how does FPSS treat this?

Does it cycle thru all the available categories in order?
Does it cycle thru randomly?
Does it select ONE category and just play THAT SS?

There's a lot of information that would be nice to have in the documentation,
but I can't find there (yet)

Thoughts?

Please check the module options at FPSS documentation screenshots.
You select from which category/ies the slideshow "pull" images and you select the way it will be displayed.

I'm sorry Katia - this is a NON-ANSWER

when someone PURCHASES a product, and takes the time to post a valid question where they've made a good-faith effort to peruse the (inadequate) documentation first, it would be appreciated if you took time to actually ANSWER the questions, not just point me back to the (inadequate) documentation, which does NOT explain the items I inquired about in the first place.

If you are going to SELL us something, I think it's reasonable to make SOME effort to HELP us.

Also, if you actually ANSWERED the question, the solution you provide would remain on the forum as a continuing help to future purchasers with the same problem. 

FURTHER UPDATE ON THIS TOPIC

If one selects more than one category in the FPSS Module,
those categories are NOT automatically viewed in sequence (even though that would be wonderful)

What DOES control the order in which slides are viewed are the selections in the ONE popup called
SLIDE ORDER...

So one should PLAN CAREFULLY when creating a long slideshow, making certain that the slide names
can sort alphabetically in the order you wish then to display, (set Display Alphabetically)
OR
that the slides are created in the numerical sequence you wish them to display in
(select Display by SLIDE ID)

Sure would be nice if that was made clear in the documentation...
