Is there a way with the blockchain.info wallet to separate wallets? For example, I'd like to have a spending wallet, but also multiple savings wallets, like retirement, health, vacation, bicycle savings wallets. And then I can choose which wallet to spend from. Know what I mean?
To avoid driving yourself insane with all of these different wallets on the same platform, pick a different platform for the different functions.
Satoshi Client - Savings
Multibit - Online Spending, Bill Paying
Blockchain mobile app - Mobile Spending
Good idea as it provides a very apparent change between 'modes' however I would recommend Armory over the satoshi client as it supports offline-watching wallets which are much better suited for savings (however you do still need the satoshi client).
