[suggestion] lock main screen for clients

[superduh]

searched "lock screen" nothing came up so i figured i'd post

it's great that the wallets can be encrypted - i think an extra layer should be to prompt for a password before the main screen for clients.
why? well, just because someone can't send coins doesn't mean they can't see what you have done with them and how many you have.
it would make sense to be able to have a password or something to open up the client's full details. that's all- thanks and have a good day everyone!
