Loading a pug file to edit, the code view ctrl + E shows it correcly, but the preview is broken 
Pinegrow v5.91
PUG files can’t be edited in PG directly.
PG can work with PUG syntax in Edit element code and Insert code in Library panel. But that’s just a helper for working with HTML. But PUG files can’t be opened and edited visually in PG.
Is this going to be added?
No plans for full PUG support at the moment.
