[Interface] Free wallpaper for a 1080p or 4K screen
1-Very necessary, since the background wallpaper (red image) is very aggressive for the eyes, the other theme (dark image) is not a dense dark, but something white with a gray tone.
With so much updating I am still surprised that this has not been improved. A 1080p that you can not put a simple photo of your collection pleasing the eye (and more having access to your hard disc), and not only see a 1 color wallpaper, but in the background an image of your choice.
2-Another great thing that is missing is to put (delete a file faster from the explorer), to a thing that is used a lot on a hard disk and to be able to delete files, since it is done enternal (it is below the entire submenu) you can delete a file or movie from your hard disk, you could assign the button (delete ) of the command to this end.
3-Shorten much more the viewing time of the characteristics of the film when you shoot forwards or backwards with the buttons on the remote. Since this information window above and below the TV, it takes a long time to come out and you are left watching a part of the movie half, when it starts to play.
