its taken me a long time to get round to playing with your app but I'm soo glad I finally have!(I didn't realise I was being blocked from downloading my purchase due to lack of space, apparently minicraft takes up loads of room
The functionality is very fluid, I went the manual way to add my passworded share and can now see all my content in a responsive manner. I've just installed ThumbGen from your suggestions and I must say the way its presented on the tv is very reminiscent of XBMC(is it a frequently used template style or is it your own work?). The whole app interface is very well thought through and a pleasure to use, something I cant say for Logitechs attempt.
There are three features I would like to request which may well have been requested before. The first being could you include support for IMDb trailers or a quick link to the full IMDb page? This would make the job of deciding which movie to watch as fluid as possible.
The second is at a slight tangent to the video side of the project. Would you be able to include a playlist feature that provides good options for adding content to it? By this I'm referring directly to one of Logitechs failings, their playlists allow you to either select one song or an album but will not let you random all your music.
The final one is probably not in your priorities for a long time, if at all, but I'll add it for completeness. I like to throw house parties and usually allow the guests to make requests. It would be a nice touch to be able to put the tv in to a graphical visualisation mode when not using the music controls, thinking along the lines of milkdrop.
Either way you have done a great job with this app, especially considering its a first attempt. Anyone who has a GTV device should get this and I look forward to seeing this project grow! Congratulations!
