I'm not sure if it was mention before, but anyways, I use subfolders for most of my systems, to separate roms (hacks, translations, unlicensed, etc.) I noticed that the web manager shows these folders when I select a system but I cannot open any of them, so I cannot edit the rom information for the roms inside nor do I see their artwork. Not sure if the developer is aware of this, but if he is, is there anything in the works to fixing this by any chance? Other than that the manager is really useful, great work!
For your proposition of design/graphic. You help is welcome ! :). We need more graphic element for communication about it. So if you want working on any graphic element than we can use for present recalbox or release about it. Say me and we can work together... But when the website would be up to date. We open more community graphic project in the forum with contest and gift to win why not :)).
