Point taken ....yes
For me though regarding the display - its the loss of the highlighting ( which you get on Tyros/psr ) When you step back from a file to its relative folder, you no longer easily know where you were and have to make a mental note..
Ok - there is an indication in bottom left as to origin of your 'current' file - but I DO miss this very simple, handy function of the display, when moving backwards and forwards in the same folder. You have to choose and 're select' the folder from main screen folder options.
