Turning an aircraft while flying has been a pain... but no longer! There's a new intuitive user interface for it! Just check these screenshots from the upcoming version v1.6

The idea about these new buttons is that for approaching or departing aircraft most of the time it's just a turn of 45 or 90 degrees to the left or right from the current path (which is parallel to the runway path: 130 and 310 degrees) is what we need. These new yellow buttons make this task easier and significantly quicker!

Please note that this feature will be included in the upcoming version ATC v1.6.
