Taking a shot in the dark here, but I THINK what's being asked is a profile and snapshot function. 1st Part..... A way to save LB/BB settings and layouts as a snapshot, so if the user goes in and plays with configs, layouts, themes, etc but it breaks or they don't like it, they can return to their original setup/layout. 2nd Part.....They want to be able to create specific profiles on a per system basis in case they have tons of media art assets for the NES, but only 3d boxes for the PSP. Feel free to correct me Colorman3605 if I have misunderstood you.
To colorman3605, while I don't believe LB/BB has a snapshot feature built in yet, I THINK you can make just a backup copy of your LaunchBox/Data folder and then you can play around with different views and layouts. If you like your original setup better, just restore the backup Data folder. I am NOT 100% sure just the Data file is all you need to back up, so may I suggest you do some small scale testing before you go crazy with it. Anybody here in the know, feel free to jump in and clarify. As far as per system profiles.....that one is above my paygrade, sorry.
Mods: Feel free to delete my post to oblivion if I have provided incorrect information....I would hate to break somebody's build due to misinformation.
