Targeted for AccuRev 7.6 - Example screen snap below.  Markdown source from https://dillinger.io/

Clarification: In thinking about this further, I believe a file preview window would be a good addition, and this markdown view could be part of it. If the file were markdown (.md) it should render it properly (bold, headings, italics, underlines).  IMHO, this should be a horizontal split with the file list in the Workspace (or Stream) explorer view of workspaces and streams.

When directory within a workspace or stream is first opened and if there is a readme file, it should be the first to populate the file preview window.  If a file in the list is selected, the file preview should then render that file.  I think the main two types that should be supported are text and markdown.  Other file types could be added, but these two would fit my workflow.  Binary files could simply say "Binary file, preview not supported".

Lastly, this should be a layout option.  Some may not want the screen space taken by it.  Also, the option should be separate for streams and workspaces due to the difference in load time between the two.  If the view is changed (e.g. select a directory, select a different view, etc.) the process should abort and start over as necessary.  It should not slow down the relatively tedious process of digging through the file tree.

Have you tried setting via the GUI under Tools -> Preferences -> Diff/Merge to use a markdown viewer?  Details are in the AccuRev CLI User’s Guide under "diff", "merge" and "ENV_VARS"

OR

I'm I misunderstanding the request?
