AFAIC, what we need is not two annoying tabs as simple/expert. It causes a lot of confusions when you try to customize the backoffice."Simple" tab is not very simple btw.My understanding of simple is ; no toolbars, no files, no visibility options, no nothing.. just a textarea and a publish button just like the below plugin.
What we need is to make the expert tab default and embed a small area for quick publishing, sth like what wp has:
Even if the two tabs will persists, such a quick post area in write panel is essential.
