Do not display directory info (size, last_mofied) : user doesn't care the folder is 378 bytes weight.
Added as Filemanager.js option : "advancedEffects" for future fading effect disabling.
Fading effects on panels are slow and boring. Making them quicker by reducing the js delay creates a visual "flash" not beautiful.
The best option (not done for the moment) is to toggle on/off these effects, so users who have "out of space" hardware and displays just one picture can be happy with fading effects and real world users who really work with the MTFM will not have to see this boring and not productive fading effect.
Not much mods for the moment :
