Intellij IDEA, scala, show all errors

Question

I cannot get any useful error reporting in IDEA 14. Errors are beautifully underlined, but it would be nice if I could see somewhere a collection of all the errors that I have in my code.

The problem monitor does not show anything, the scala facet does not load, I'm lost.

I would be pleased with a window that would simply collect all the errors that I emphasized in my code, or functionality similar to the F2 shortcut (go to the next problem) if it works on the whole solution, not only inside the file.
