How do I hide or at least sort all files I use in the game - NW>JS Export?

When exporting my game with NW.JS, all imported files are smack in the main folder of the game. Every dialogue json, banter json, ogv etc... . Is there a way to hide these or at the very least make sure they exist in some sub folder? Thanks!

Also, is there a way to remove F12 starting dev mode from the game.

Cheers!

Tick 'Package assets' on export. It can make the app take a bit longer to start up though.

Thanks a million!
