Working with Multiple Projects

Hi,
Since I am expecting to make a fair few (MVC) custom widgets, I was hoping to keep them I a separate project. The reasoning is that I do not wan to clutter up the Sitefinity application, and wan to keep my own stuff separate.
Does anyone know if it is possible to create a separate MVC project in the same solution as the Sitefinity project? and if so how can I ensure that the widgets I create in my project are displayed in the toolbox of Sitefinity?

Any help would be great on this.

I have not done it with a MVC project but you should be able to do just as you could with standard user controls ASCX files

Here is how to register a widget
