Could we get a year column when listing discs? I mean the listing when you go to "Discs" and then click one of the categories; or when you do a search like "command". While all the info in the listing is nice, I am missing this little data for the listing to be really valuable.
I also think that a "year=" tag in the XML datfiles would do no harm. Actually any data could be put in the XML datfiles, like disc number id and such, but I think I understand they're not data oriented but file oriented so maybe adding the year would lead to more requests to put even more info in the datafiles, and that might not be what you wanted. It would be close to make the whole DB generally available, and if you haven't done it yet, I guess you have your reasons.
So in short, with the first suggestion I would be more than satisfied.
