Rob Day here, adding a number of observations about various Studio tabs; feel free to deal with them as you see fit, some of them are admittedly aesthetic choices:

First, about the "Application Settings" tab and its sub-choices. I would relabel that as "Project Settings" since all of the other online docs constantly refer to Studio "projects" so this should be consistent. And once you get into that tab, the top text could just read "General project settings". Also, under "Settings" there, it looks like the Project Name is user-changeable – I wasn't aware that users were allowed to change their project name. Is that true? And under the Manifest tab, the top text doesn't make it clear why the user would be interested in this content. Since the user can't edit the Manifest text itself, what is the user supposed to do with that information? Why would he care about it?

Under "Global Settings" -> "Branding", I think it would be helpful to add to the top text that one must first upload the image files to Resources before you can select him here. That might seem obvious, but I didn't realize that the first time I tried to set a brand.

UPDATE: I notice under the Resources tab that it explains that images will be uploaded under "/nuxeo/img" while widgets will be uploaded under "/widgets". But why would the Studio user need to know this? Wouldn't he simply select resources by their name? Why would he need to know the upload directory names?
