New Wallet Features?

[greentea]

So besides the standard wallet functions ...

what are your top 3 features/functionality you'd like to see in a wallet?

 Looking for ideas in creating a new kind of wallet.

One where I don't have to download the entire blockchain, but is more secure than multibit.

I think multibit only downloads the block headers and trusts the nodes have not changed the block's content.

There must be some way to check the blocks in the cloud without downloading them.
