How do I delete a project?

In RunbyMine 4, I used to be able to close out of all my projects, and at that point, I can see a dashborad that allows me to delete projects. I can no longer find that dashboard in RubyMine 5.

I tried to manually (from the Mac Finder), deleting the project files, but when I start RubyMine 5, I can still see the deleted projects in the leftmost window.
