1. In addition to the max count of matches to look for in the pattern settings dialog, an additional field that shows the actual match that was found within that max count would be a good one as the pattern settings dialog shows a pretty small image and making out the count is not that easy. Some times even the page elements might make it difficult to make out the matches shown on screen.
2. Might also be helpful if we can tag a superscript or subscript number that shows along with the matched images to denote the order in which they were identified. This can be an option that can be turned on and off from the pattern settings dialog itself.
