Does anyone have practical experience or an understanding of the engine that 
would cast light on the relative speed of some alternative ways of doing 
things?  I want to switch among a number of different groups, each of which may 
contain its own fields, graphics, buttons, and images.  Possible approaches:

- Have many different cards, each with a group peculiar to it, and GO TO each 
card as desired, or

- Have one card, with many different groups, and SHOW/HIDE the groups as 
desired, or

- Have many different cards, each with a group peculiar to it, and COPY a group 
from an unseen card to a single card that is always seen (and DELETE the 
unwanted group on that single card).

There are other considerations that affect a choice among these methods, but my 
concern here is the speed with which I can switch from displaying one group to 
displaying another.   I am wondering whether at some level these methods all 
amount to the same thing from the engine’s point of view (since everything is 
in RAM in any case).

Many thanks.

David Epstein
