I cannot seem to be able to find the setting to enable line numbers for all files, but I have to always right click and enable this on per file basis.
There must be a global setting for this, right?
Version 2.6 and above: PyCharm (far left menu) -> Preferences... -> Editor (bottom left section) -> General -> Appearance -> Show line numbers checkbox
