Just an idea, makes sense to me but wondering if anyone else likes the idea at all? in the picture if you keep pressing left you will be taken back to the top rollers to exit the view you are in. How about if you keep pressing right a side column pops in just like how you can swipe in menus like on some ipad apps (gmail app comes to mind)..
There could be some useful options displayed with icons such as toggle access control (which could be set on or off with a four digit pin on the remote), party mode, zone etc. I realize this goes against how pressing right works when you are drilled down into the file list, as pressing right will go to the secondary roller and show watched and so on.. But in defense of the idea there's no real need to press right on a file to get on the secondary roller when you can just press enter or ok on the remote and some of these toggles like this would be much easier to access than having to drill down in to the more menu on the top roller..
