I usually edit pages longer time while I add larger amount of content. In this time I check the preview several times. Earlier there was a dedicated button beside the SAVE button for preview. In the new wikitext editor I have to go through the Publish page pop-up to be able to click on the preview button.

Is there a way for a dedicated button beside the publish button for this function (available directly from the editor)?
(Maybe as an opt-in or optional feature?)
