Sure. Actually this caching is already being done. If the state of the
packages in your system have not changed, APT will open a lot faster
than when you've just run update, or has just removed/installed some
package. Unfortunately, it's still a heavy operation.

Hummm.. I think I'm missing something here. Isn't this exactly what was
asked above?

Given that there's already a non-interactive option, in the menu, I'm
not sure if changing the behavior of the find bar is really necessary.

Btw, I prefer "Programmed Changes", since the changes are not really
"enqueued", but that's just personal taste.
