How do I disable the split-screen/two-pane layout showing posts and comments side-by-side?

Hi everyone,

I’m new to Continuum and I’m trying to change the layout. At the moment, Reddit posts are displayed in a split-screen view where the post content is on the left and the comments are shown on the right.

I’d prefer the normal single-column layout where I can open a post and then scroll through the comments underneath it.

I’ve looked through the settings but can’t find an option to disable this. Is there a setting for turning off the tablet/two-pane mode, or is this behaviour automatic based on screen size?
