[SOLVED] Create a project version

Hello,
I am a new user of projeqtor. I am really impressed by your application. I would like to use it as a project management tool for the projects I am dealing with in my company. However, I would like to ask you few questions :
1- I am interested about the "Screen customization" plugin. I would like to know if it is possible to get a demo version before buying it.
2- I am using your tool to import projects with their specifications. When I enter a new project with its specifications, activities, affected resources, milestones, billing ... I need it to be validated by the customer. In case the billing is not validated, I have to change some fields on the current project's screen. That's why I need to set a project's version linked to these few changes. I would like to know if it possible. We can do that with a product.

Best Regards
