Better error signs in code editor

[dipacs]

It's hard to find the line with the problem if it's just underlined with a red color, especiallly in dark mode. Please place an error badge in front of the line. A good example is eclipse, netbeans or IntellyJ where the line number is replaced with an error badge.
