Netbeans? There is a drop down of all open tabs, but that can't be filtered. There is also a window which shows open documents but for some unfathomable reason it can't be docked.

The only navigation I can see for open projects is the tree view which is painful for large projects with files scattered across the project (e.g. web frameworks).

edit: Ah, I see. The article wasn't about text editors. It was about how file navigation (within whatever environment you use) sucks.
