since the wordpress forum seems to be dead I’m asking it here again.
I’m actually working to switch a existing newsletter from the old theme based editor to the composer.
The old newsletter theme use a width from 750px instead of the 600px which are hard coded for the composer. I haven’t seen a update-safe way to alter that.
What is the reason that this parameter is hard-coded and can’t change either by a hook or anything else?
Also the newsletter use OpenSans and I haven’t found any info to add a new font family to the font select or is there a reason that this select box cannot be extended?
