We do that all the time. Try this in your view
<view autoCancelInterval="90" isVisible="true" onunloadCancelJobs="true" refresh="-1" template="dashboard.html" >
<label>YOUR VIEW NAME/TITLE HERE</label>
<module name="AccountBar" layoutPanel="appHeader">
The label tag could read, "Welcome to ABC Company"
Note in particular that the accountbar mode parameter is "popup".
If you want to get fancy, create a graphic named appLogo.png and put it in the appp\appserver\static folder of your application. Make it something like 436x60 pixels. Then edit application.css to match the image size.
background: url(appLogo.png) no-repeat 0 0;
_background: url(appLogo.gif) no-repeat 0 0;
That should give you the customization that you want.
