Problem:

I have some post forms to edit existing content and I need a way to either hold the edits the user has made until they're reviewed

Solution:

There isn't such kind of built-in feature, the editing post form will override the custom field values, so the original field value will lost after user submit the editing post form.

As a workaround, you might consider these:

Problem:

I'm trying to create a navigation from list of posts.

I need to make the current page in bold and first item.

Solution:

You can use [wpv-conditional] shortcode to check if it is current post, then display different styled link, for example:
