Should be nice to provide a way to retrieve any parameters following a "nw.exe" using the node webkit plugin.
Example : Renaming a "nw.exe" into "nw.scr" is working fine to create a Construct 2/Node webkit windows screensaver but i don't find any C2 way to retrieve parameters send by windows to change my project behaviour and make it more compliant with standard screensavers management.
Note : The new node webkit 0.7.0 release seems provide new ways to retrieve this parameters but this version is also full of bugs so it's perhaps better to wait for 0.7.1 ;p
