I prefer to use library view over theatr view for a number of reasons:
1. You can see both tiles, and grouped lists
2. You can jump from one grouping to another without having to go through the heirachy in order
3. You can change viewschemes quickly as they are all on display in the tree on the left
But on my 720p HDTV there is such little vertical resolution that seeing the files list and the tiles on the screen at the same time borders on impossible. There is plenty of horizontal resolution though. Could we have an option to view the files list on the side of the tiles rather than underneath?
