Byteflow has a feature when authoring blogs that allows you to save your post as a draft. I use it constantly, but someone requested via a ticket to have a “Preview” option, allowing you to see your blog post (logically the same as saving it as a draft) before you post it. If anyone is interested in utilizing a “Preview” option, see the patch below. Basically all it does is utilize the draft option, but takes you to the generated draft to “Preview” it before you make it public. I don’t think it will be committed into the code base, but if anyone is looking to have this functionality now, see below code.
