I just implemented the Ultimate Branding plugin and I was hoping that the Custom Admin Bar would have the option to create menu items in the same manner that you have done on wpmudev. The only option I have found is to add drop down items under my logo/name. Very surprised that you didn't add the ability to add top menu items and then define drop downs for each of these. Especially given the fact that you have done that with your own site.
I really like everything else about the plugin but the above was quite disappointing.
For the moment I have custom coded the menu items that I needed but for management purposes it would have been nice to see this as part of the plugin.
Overall I still give the plugin 5 stars as managing the half dozen old mu-plugins for re-branding all in one place is fantastic.
