Some times the usability on PP is compromised due to a confusion on what is from PP and what is from Companies.
I mean that it is a little bit confuse the Administration treating the PP's configurations in the same place that are the Company's configurations.
Project, for instance, uses the PP but are part of Company data. To create a project I see PP configurations and Company configuration. It is a little bit fuzzy.
If I want to install a plugin or create a contact I must use the very same menu. This should be separated, what belongs to Company should remain under company's administration and what belongs to PP should remain under PP configuration.
