Board Export : Ability to filter which cards in a list to export#98

Currently, Board Export allows you to export lists in Trello. However, if the list proves to be too large, the process may take a long time.

It would be great if we could filter which cards in the list that will be exported. For example, only 5 out of a list of 50 cards, or even only one card with important information needed to be exported.
