@elextr No, that's completely not what I meant.
I mentioned this in my initial report. If I click `Next error` the cursor jumps to another line. BUT I like to know the error for the line where I put the cursor.
Most editors / IDEs somehow show you the error for the line where your cursor is currently in (if there's an error). Some editors display popups, some highlight the error in a pane below. The thing is, sometimes it's not helpful to go through the errors in order the compiler has given them to you. This is especially true for [Rubocop](https://github.com/rubocop/rubocop) which only reports soft warnings, not hard errors.
