In Snippet Reviews the comments are located in the right-hand side while in normal reviews they are inline.

The display on right hand-side like in the Snippet Reviews is much better. What is also missing in the Snippet Reviews is to fold comments and replies. Currently you can only choose to hide or display, but what users really want is to see the context and the relevant information, therefore you need sometimes a fold mechanism to focus on the relevant parts.

If screen width is the issue, the file browser has a hide icon, therefore it would make sense to have an additional option to show speech-bubble on the right-hand for all review types.
