+### KeyChainManager / idStore 2.0 (maybe just in MetaMaskController)
+	keychains: []
+	getAllAccounts(cb)
+	getAllKeychainViewStates(cb) -> returns [ KeyChainViewState]
+
+#### Old idStore external methods, for feature parity:
+
+- init(configManager)
+- setStore(ethStore)
+- getState()
+- getSelectedAddres()
+- setSelectedAddress()
+- createNewVault()
+- recoverFromSeed()
+- submitPassword()
+- approveTransaction()
+- cancelTransaction()
+- addUnconfirmedMessage(msgParams, cb)
+- signMessage()
+- cancelMessage()
+- setLocked()
+- clearSeedWordCache()
+- exportAccount()
+- revealAccount()
+- saveAccountLabel()
+- tryPassword()
+- recoverSeed()
+- getNetwork()
+
+##### Of those methods
+
+Where they should end up:
+
+##### MetaMaskController
+
+- getNetwork()
+
+##### KeyChainManager
+
+- init(configManager)
+- setStore(ethStore)
+- getState() // Deprecate for unidirectional flow
+- on('update', cb)
+- createNewVault(password)
+- getSelectedAddres()
+- setSelectedAddress()
+- submitPassword()
+- tryPassword()
+- approveTransaction()
+- cancelTransaction()
+- signMessage()
+- cancelMessage()
+- setLocked()
+- exportAccount()
+
+##### Bip44 KeyChain
+
+- getState() // Deprecate for unidirectional flow
+- on('update', cb)
+
+If we adopt a ReactStore style unidirectional action dispatching data flow, these methods will be unified under a `dispatch` method, and rather than having a cb will emit an update to the UI:
+
+- createNewKeyChain(entropy)
+- recoverFromSeed()
+- approveTransaction()
+- signMessage()
+- clearSeedWordCache()
+- exportAccount()
+- revealAccount()
+- saveAccountLabel()
+- recoverSeed()
