How to show access modifiers for classes in IntelliJ IDEA?

I've recently upgraded to Intellij IDEA 2017.2 and access modifier icons disappeared from my file tree... How to get them back?

Solution 1:

UPDATE

Since 2019.2 version you can enable it in the Project view options, toggle the Show Visibility Icons:

For older versions:

This option was disabled intentionally, see this comment for the explanation:

This information was intentionally removed, as we believe that it brings more clutter than actual value.

To enable it back add -Dide.projectView.show.visibility=true in Help | Edit Custom VM Options.

Solution 2:

Since 2019.2 there is actually an easy to use option as described in comment:

you can find this setting in options menu of Project Tool Window. It's called "Show Visibility Icons"
