Please do remember, find a easy folder to save the wallet file that the user need to back up.
Don't put it at %APPDATA%/bitcoin anymore.For geeky it's easy, but for average users it's difficult!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Better yet: a simple
"Export wallet..." button in the GUI. The
backupwallet RPC call is already implemented, so it should be easy if you know Tk and C++.
