After our discussion about the OPDS server, I made some changes to the normal and mobile content servers. I haven't yet submitted these changes to Kovid because I wanted to check to see if they are useful.
I added custom field values to both servers. The result is similar for both, so I will show the mobile one here. The text shown for one book with several custom fields is below. The output does not contain <br> elements, so it wraps wherever the browser wants to wrap it.
Code:

Is this helpful? Should it be changed in some (possible) way?
