Since the introduction of the Account model we have to deal with two different models in the #BitShares reference Client GUI, Wallet and Account model.
This has raised numerous questions in the support channels and often it is not obvious which model the user has chosen.
Here are my suggestions to ease the user decision to choose a model and how each model is presented in the GUI.

First I suggest to simplify the account creation page in the GUI by adding a simple radio button question.

Are you new to BitShares?

Yes (show Account model/grey out Wallet model)
No (show Wallet model/grey out Account model)

Account model text

Account model

The Account model is for beginners as you can use your account and password on any BitShares Client at the same time without additional steps. It provides higher convenience but it is less secure then the Wallet model. However you can start with the Account model now and upgrade later to the Wallet model.
Use a strong password, ideally 20+ characters!

Single account
Easy login
Moderate security

Wallet model text

Wallet model

The Wallet model stores your BitShares wallet on your computer. It is encrypted with a password of your choice, and can be backed up by either using a brainkey or an encrypted binary file that contains all the private keys. You can create multiple accounts in your wallet and it is more secure then the Account model, but it is restricted to your current computer or browser. To use your wallet in another browser or computer, you must import the wallet backup file or brainkey.

Multiple accounts
Wallet file backup required
High security

Secondly, I suggest to change how each model is presented in the GUI as followed.

Detect if Wallet or Account model is enabled.
If Account model is enabled show ACCOUNT in header menu and sub-menu OVERVIEW as account page
If Wallet model is enabled show WALLET in header menu and sub-menu OVERVIEW (all accounts) and ACCOUNT as account page
Also if Wallet model is enabled make "Active account" field in header menu a drop-down list to select a different account from wallet.
