I’d really love to use this plug – it looks to be well made – One thing stopping me though is that the ArtistDataPress Layouts/ custom | classic has no save function. I can only use classic, which unusable on the site I’m building. FYI it’s a subsite in a WordPress multisite.

I would normally simply go to mysql to flip this, but I’m on managed WordPress hosting that wont allow that access
