0.8.3 should have the dashicon support aready. It just co-ops with one of the existing fields, I can’t recall which one right now. It is one of the text fields.
Sorry, about that. I overlooked it. Under ‘Advanced Options’ > ‘Menu Icon’
So can we use the Glyph (\f128) or use another method for using Dashicons?
Should be able to fulanoinc. All we do is provide an text input and the correct sanitization that still allows for it but will still keep things safe. Otherwise, we don’t limit it in any known way.
