I usually use "create card" rather than "clone". I suppose this is personal preference, but it seems cleaner to me. A newly created card will automatically include the background (provided the group's backgroundBehavior is set to true,) so unless you need to copy over specific card properties, "create" works fine. If you've set up a bunch of card properties that you want to retain though, then cloning is one way to carry them over and you could use that instead. Another (possibly preferable) way to set up card properties is by setting properties in the templatecard before creating new cards.Using "create card" rather than clone can be really important if you are using groups. I recently rescued a stack for someone when it was taking about 7 seconds to go to the next card with no apparent messages in the way. The stack had over 400 cards and it was a data stack with each card containing the same objects. Although the objects were mostly in groups (2 groups per card) they were not set as background groups and the cards had all been made using the "clone" command.
The main effect of this was that there were over 800 separate groups in the message passing hierarchy which seemd to be what was delaying everything! The stack size was over 21 MB, loading & saving took for ever and it was really unresponsive.
By re-building the stack with just 3 background groups and using "create card" to make the cards, I got the stack size down to 1.9 MB (after importing all the data) and with the normal instant response times to clicks and arrow keys.
Cheers, Sarah
