Currently, to use a different repository server, you have to run the configuration wizard multiple times.

It would be much more convenient to be able to open the Plastic SCM tool and click "add new server..." or "select repositories from server..." so that the user can choose where to get a list of repositories (projects) to work with - and start creating workspaces to pull the project down to.

The following is a scenario I ran into:
1) I created a local plastic server to replace my personal CVS server for projects that I work on at home. Using the configuration wizard works fine for that - assuming I will only have a SINGLE plastic server.
2) I decided that I wanted to ditch CVS/TFS at work and replace it with plastic - however, I also often work from home - now I have to configure my WORK server through the plastic configuration wizard. Which DROPS my original configuration. I can create workspaces from the NEW server, but have no ability to create workspaces on the "old" (meaning, personal/home) one until I switch the active server - by re-configuring it through the configuration wizard - thus dropping my Work server configuration.
