Does NetBeans have a way to show all the editor hints (like missing braces, unused imports, etc.) for a project? Ideally, they would show up in the Task List, but the warning icons in the project view would be fine too.
Right now, the best I can do is to open each file and look at the color indicator next to the scrollbar.
As of NetBeans 7.2, there's a new "Inpect" window (go to Source > Inspect...) that will show all the hints for a project. You can also install additional inspectors, like FindBugs, and those hints will be included too.
