Defining field properties of similar views in only one place

You cannot share any settings between projects. Usually it makes more sense to keep the number of projects down restricting access to different areas of your project via user group permissions.
Another option - create a separate project that combines several common tables and views, setup fields and tables the way you need, save it as a template and then add this template to multiple projects. I have to add that this approach can be a real headache if you have to make more changes to those common tables and views.

Dear Sirs,
It's OK what you say, it makes more sense for me just to unify in only one project the 27 ones I have by this moment. Take into account that this project will have hundreds of options, even making that each option appears only once. So, in order with your advice, I have two questions:

1. How long would it take to PHPRunner to open this huge project? (even assuming it is stored in a local workstation just to make this process faster). The PostgreSQL database resides in the same VLAN, in a Linux virtual machine server. Do you think that PHPRunner 6 or 7 would perform such a huge opening task in a reasonable time?
   
2. I am not alone in this job. Actually we are two people working on it. So, is it possible for both of us to work simultaneously over the same project (each one modifying different areas of it)? What about the impact on the .phpr file and/or the hole project, assuming that one save the changes after the other did? Does PHPRunner offer any kind of collaborative way of working?
   Thank you in advance.

I have no idea how long would it take to open your project. Download trial version and give it a try.
