I have been using other editors with the Fira Code font that support ligatures and now I cannot go back to write code with it. For example VSCode, needs to be enabled on the settings, now I write most of the PHP code on VSCode then debug and fine tune it on PHPEd. I think PHPEd is almost there, because when code or comments are folded and the mouse is hovered on the folded section, the popup code shows with ligatures!
If you don't know what font ligatures is and how convenience they are, take a look at this:

Remove the spaces on the URL.
Dmitry, once PHPEd supports ligatures, add yourself to the list of editors where Fira Code works ("free" PR).
