I would also like to see not a little but a lot more information out of the integrity check. The "Item" column lists names at best (or just the object type); if this could be split into "Item Type" and "Item GUID" that would help A LOT.
Also, having the option to Find in Project Browser, as well as a selective Resolve (which would carry out the Proposed Action on only one item in the list) would be fantastic. I know it won't be relevant for all reported problems, but it will be for some.
Yes it would be better if this tool were never needed, but that's a meaningless argument. There are a thousand and one reasons why a database can go out of whack, many of which have nothing to do with the quality of the client software.
Better repository management tools would be really useful, especially for larger installations.
