Show all problems with severity "error" in project view

Files containing syntax errors (file1.php) are highlighted in the "Project" view, including all folders up to the project root, so the problem is obvious even if the folders are collapsed. This is nice and immediately makes it visible that something is wrong somewhere. However this does not work for other types of problems with severity "error", problems which just as much result in code that won't work at all. In those cases (file2.php) the error only shows in the editor. Of course I can manually run code inspections, but seeing these fatal problems immediately would be nice. Can this be enabled somewhere? (It might even be useful to show problems with lower severity.)
