I want to request a preview button. It should be available to all (incl. editor "none").

Press the button in the bottom-right corner of the textbox to preview.
I never clicked that. Looks like a right floating code editor button. I'm talking about a plain simple preview button ;)
I hacked a preview into Extension:ArticleComments by using the API to parse the text above the textarea. It's rock solid.
I guess this GoodUI hint applies here: Try Icon Labels instead of opening for interpretation. https://www.goodui.org/#47
Making the switcheditor button more intuitive (it is a toggle to switch between wikitext-mode, and VE-edit-mode (essentially a preview, and hence used as such)) is now tracked at phab:T101316.
A feature-request to make a separate more classic-style 'preview' (that cannot be typed in, and is not VE) is tracked at phab:T69258.
