I noticed that we have > 2200 sources listed (and growing) and researching the matter seems to indicate that I can use a transformer based approach to prevent this from continuing to occur. But this raises a couple of questions:
1: What is the downside to having "zillions" of source files listed. Is it a performance consideration, or just a convenience issue from the standpoint of the user being able to select a specific source file?
2: Even though one can correct the issue going forward with a transformer based approach so that the source files won't continue to proliferate, what can be done to collapse the existing 2200 displayed source files, or to remove that clutter from the Sources window on the Search screen?
