Xcode, how to updates "Recent" projects

I have a list of projects i am working on, some of which are no longer relevant. I would like to be able to remove them from the "Recents" list that shows up when Xcode starts up.

How to remove projects from "Recents" list?

Please let me know

Where is the project navigation pane in Xcode?

At the left and right of the project window, as you surely know, are the Navigator pane and the Inspectors pane, respectively.

You can clear the entire recent projects list via the "File" -> "Open Recent" -> "Clear Menu" option within the file menu. (This applies to Xcode 4.x, but there's an equivalent in Xcode 3.x in the event it's not in the same location.)
