 # Code Requests
 
-- Support for undo-ing an action (This will need the implementation of an undo stack)
+- define **Radixx.attachMiddleware(function: fn)**
+
+```js
+
+	// below is the form of the implementation
+
+	Radixx.attachMiddleware(function(aciton, next){
+		if(action.actionData === null){
+			action.actionData = [{}];
+		}
+		return next();
+	});
+```
+
+- modify **Radixx.createAction(object: obj)**
+
+```js
+
+	// below is the form of the implementation
+	Radixx.createAction({
+		// used to identify an action
+		'doThing':{
+				type:'DO_THING',
+				// define what the payload for this action should be and look like
+				payloadDefinition:[
+					Radixx.Payload.typing.array.isRequired(),
+					Radixx.Payload.form.object.asPart()
+				]
+		}	
+	});
+```
+
 - Optimize <q>onDispatch</q> event not to fire only when any store data ACTUALLY changes
+
+- See if there's a way to stop the propagation of _'storage'_ events whenever **Radixx** is making use of sessionStorage
+
+- Detect memory leaks and clean them up.
