Status supports 3 sidebar layouts (left, right, none) and 1 or 2 columns. You can find these options (and lots more) in the theme customizer.
You can change the sidebar layout for your homepage, archives, search results, posts and other pages by going to Appearance > Customize > General Theme Settings > Layouts.
Just click on each option and select from the drop-down box (the default layout is a right sidebar).
You can change the columns layout for your homepage, archives, and search results pages by going to Appearance > Customize > General Theme Settings > Entries.
You must first select your Entry Style (select Grid if you want two columns).
From here you can also edit other entry options for your excerpt, thumbnail, and more.
