Hi Alexander,
First, I want to clarify that this toolbar is NOT a feature of the CMS. The CMS provides some convenient admin links, where they are located on the page and how they are dressed up is completely up to skinning. This toolbar was a neat thing I added it to most of the skins because it seemed cooler than what we had before. You don't have to use the toolbar I made, you can make one to your own liking or modify the one I made, you can change the text of the show button in your layout.master.
We include a number of skins with mojoPortal to give people a good start on their custom skins, it is not my expectation that people will use the included skins as is though they are free to do so.
Many of the skins have similar elements in common not because it is the only way to do it, but because they are all maintained by me and I happen to do it similar.
Best,
Joe
