Yea, I 3rd that! Ive talked to a couple devs about these icons. They said when you increase the cache for thumbnails theres the risk things might run slow, or not work... but from my experience so far, I see NO decrease in speed at all. Everything runs smooth, and im viewing about 40 folder wide icons altogether, and the resolutions of these icons are at 480x82...
Its hard to get something like this implemented to xbmc, unless they feel it is something that people need or really want
and as for the requests of Battlestar Galactica & Grey's Anatomy, I should have those done tonight for you, and uploaded to the site,
http://xbmc.ckdvt.comIf you have ANY requests for some wide icon TV Shows that you need, let me know, I will fulfill that request that day!
