Members can be marked as Favorite. Favorite members appear first in the member list and have a yellow background (default). Using favorites helps repeated navigating within the same set of members (methods). For example, if you're working on a specific feature, you usually need to navigate between several methods involved in the feature implementation. Marking these methods as favorite, groups them and brings them to the top of members view, speeding up navigation. To toggle a member's favorite state, use Ctrl+Shift+F in either the Members view or in the IDE editor.
