-Multiwallet Qt Development and Integration Strategy
-===================================================
-
-In order to support loading of multiple wallets in bitcoin-qt, a few changes in the UI architecture will be needed.
-Fortunately, only four of the files in the existing project are affected by this change.
-
-Two new classes have been implemented in two new .h/.cpp file pairs, with much of the functionality that was previously
-implemented in the BitcoinGUI class moved over to these new classes.
-
-The two existing files most affected, by far, are bitcoingui.h and bitcoingui.cpp, as the BitcoinGUI class will require
-some major retrofitting.
-
-Only requiring some minor changes is bitcoin.cpp.
-
-Finally, two new headers and source files will have to be added to bitcoin-qt.pro.
-
-Changes to class BitcoinGUI
----------------------------
-The principal change to the BitcoinGUI class concerns the QStackedWidget instance called centralWidget.
-This widget owns five page views: overviewPage, transactionsPage, addressBookPage, receiveCoinsPage, and sendCoinsPage.
-
-A new class called *WalletView* inheriting from QStackedWidget has been written to handle all renderings and updates of
-these page views. In addition to owning these five page views, a WalletView also has a pointer to a WalletModel instance.
-This allows the construction of multiple WalletView objects, each rendering a distinct wallet.
-
-A second class called *WalletFrame* inheriting from QFrame has been written as a container for embedding all wallet-related
-controls into BitcoinGUI. At present it contains the WalletView instances for the wallets and does little more than passing on messages
-from BitcoinGUI to the currently selected WalletView. It is a WalletFrame instance
-that takes the place of what used to be centralWidget in BitcoinGUI. The purpose of this class is to allow future
-refinements of the wallet controls with minimal need for further modifications to BitcoinGUI, thus greatly simplifying
-merges while reducing the risk of breaking top-level stuff.
-
-Changes to bitcoin.cpp
-----------------------
-bitcoin.cpp is the entry point into bitcoin-qt, and as such, will require some minor modifications to provide hooks for
-multiple wallet support. Most importantly will be the way it instantiates WalletModels and passes them to the
-singleton BitcoinGUI instance called window. Formerly, BitcoinGUI kept a pointer to a single instance of a WalletModel.
-The initial change required is very simple: rather than calling `window.setWalletModel(&walletModel);` we perform the
-following two steps:
-
-	window.addWallet("~Default", &walletModel);
-	window.setCurrentWallet("~Default");
-
-The string parameter is just an arbitrary name given to the default wallet. It's been prepended with a tilde to avoid name collisions in the future with additional wallets.
-
-The shutdown call `window.setWalletModel(0)` has also been removed. In its place is now:
-
-window.removeAllWallets();
