Bring Back Single Column & Photo Gallery

I'd like to have the single column added back to Wix Forum but the images inserted need to not be so huge on the feed.. Please bring single column back. I don't see it in my editor options anymore. Also I'd like for Wix to bring back Gallery when inserting images in posts on the forum. It was one of the main reasons why I got Wix for its forum purposes because it was one of the biggest things our members loved when I had created the site before our Google+ group was closed.
