Well, I send yesterday some suggestions to the support team for improving the firmware, here they are.
1) Posibility to search files by name (especially video files), maybe adding a keyboard like the wifi settings could do the work?
2) Make the list of files "circular" to improve scrolling, so when you are in the last file, if you make another move down, it will scroll to the first file (and the same if your ar the first file and move up, it would go to the last one). Same thing for the page scrolling with the fast forward/rewind function.
3) Option to turn off file info in the left bottom corner. With some files I see that the media player brings some content of the file (ie file size). But the player takes some time to aquire this info, so if you are scrolling, the scroll slows notoriously. If we have the option to turn this off, it will have the normal speed, and maybe we could use the info button of the remote to aquire this info.
They told me that 2) and 3) should be easy, and the the RD team may do them with D2.41 1) is more difficult so it should bet later after 2.41.
Maybe if you have more suggestions we could send it to them!
