Is it possible to set one colour for // comments and another for # in PhpStorm IDE?
I would like to use # comments for short descriptions on how the code works or for indicating some sections in classes (like # Accessors, # Calculations etc followed by adequate methods) and // for temporary comments. For this it would be extremely helpful to have different colours.
I don't think this is possible with default PhpStorm setup (hope I am wrong), but maybe is there an plugin for such thing?
Not possible ... and existing ticket has "Backlog" state (maybe one day, low priority).
