Advanced Guide Listing
I have the TVLISTINGS plug in and it is very nice. But one thing I would like would be some more modification to the display which I think cannot happen without some DB calls. I'm sure this could be slow to display or generate at the point of wanting to review the guide, but I'd like to see only the programs I have not recorded. Or maybe just assigning them a different or faded color so I can scan the guide more quickly.
I would assume that the guide is built when it downloads, so basically it should be ready for display when asked for and won't have to build on the fly or at your request.
