How to delete Project in IDE?

In general, maybe you planning to create menu with item "Open project"? I'm confused without this menu. Open project by "Reopen" - isn't "intuitive" design.
I've created some project for test, now i use my normal projects, but that old one still holding in project's list. So, question is how to delete project? Delete from folder manually - is simple, but not actually elegant (and not normal) way.
