In the Search Scope window, the sources are listed there. But it can be quite confusing when a few sources are with the similar names but in totally different directory (e.g. sources are C:\users\Tom\docs, C:\users\Dave\docs, docfetcher displays them as "docs" and "docs"). And I failed to modified "tree-index.ser" to get the source name renamed. Is it possible that you can add a feature that by double clicking the source name, the name could be renamed or similar renaming feature? If not, can you point me some hint that I can manually rename it by modifying index data?
