The "sliding window" is  the exact concept i'm planning to implement,
but without an explicit "more.." button. I would simply keep
track of the current window (actual record in the pdb) and
of the selected item (offset into the current window/record) and 
automatically switch from a window to the other.

I think the list will not be used to randomly search an item,
but to browse items that are closer to the searched one.

I would like to implement some kind of search. obviously a linear
search is not an optimal solution. maybe i could keep track, for each record,
of the min and max id of the encapsulated products.

And i must also keep the whole thing sorted...
