Squarespace got back to me and said too bad, they know about it, it's not fixed and there is no workaround. So if you have a portfolio site on squarespace and God forbid more than 60 images, and you want to move them around, you can't. You are just stuck with what squarespace gives you.
Has *anyone* else used the paid 3rd party plugin? I don't know who makes it and I don't want to install some kind of spyware on my site. I'm referring to the plugin mentioned earlier in this string: https://www.squarewebsites.org/products/squarespace-admin-ui-tweaks
Thanks!
