问题
Today I bought PhpStorm and set it up with new settings, but unfortunately I don't know how to remove this vertical line in the editor (as you can see in the picture below).
回答1:
Settings/Preferences | Editor | Code Style
That would be Hard wrap at and Visual guides fields.
Please note that some languages (e.g. PHP etc) may have own rules for that (override aforementioned ones).
