rex is a great coder, but he does divide his plugins an aweful lot for modularity.
First rex has a repository tool you can install. It's not hard to google rexrainbow repository
My next piece of advice. Don't bloat your plugins. Only Rex can help you with his plugins and some of them are obsolete. Be selective. Also not all devs on the forums will help if they have to install more capx than they feel needed for their own use.
