In reply to Unai.

I do use the mode to write my content with little distractions but near the end, I probably click save draft and preview at least 5 or 6 times while doing edits before hitting publish. When DFW mode is activated, all it does is hide the meta boxes, making it not much different from the default mode. So why should I turn it on and off which is doing the same thing as fading in and out.

Ultimately, I'd like to see iterations continue on the feature so that one day, we have just one editor with one writing mode that nails the experience for most content writers.
