I am just wondering why the html view on the WYSIWYG tab minifies everything. it is pretty much impossible to use. It also does not allow tags such as <hr> and others. Is there any way to get this to behave a little more like the built in WordPress content box? Clients are having a lot of trouble here.
@elliot, thanks so much for looking into this. I just started working with ACF and it is freakin awesome. I just happened to notice today that the HTML in the WYSIWYG seemed to be minified and then came across this post. I would be very happy if it can be made to emulate the native WordPress editor, but I also understand if it is an issue with tinyMCE object.
