The only place where a not so short Spotlight comment can be fully read in DT is in Show details, with the zoom slider nearly to the maximum, in icon and split views.
Agruppated by tag (in my case, topic / publication), this could be the only and perfect view to read them. However, at this level of the zoom slider needed to show Spotlight comments there is so much info in between each comment (kind, label, size, added, created, modified, path, url) that the Show details option is also unusable for that purpose.
I would like to suggest three possible solutions:
a) The fields to display could be chosen in View > Columns, as for the other views.
b) A template to modify this view, so that the user can choose the fields to be displayed.
c) A three column sheet layout: one for the icon, one for the file details and the last one for the Spotlight comment. So that in the last column the user would be able to read only the Spotlight comments from top to bottom of the page.
I think the last suggestion is the easiest to implement.
Additionally, if the columns of the sheet are selectable (not only rows as it is now), the user would be able to copy all Spotlight comments (for the topic or publication, etc) in order to paste them in another file -for reference to write a review or whatever purpose.
The last paragraph is actually another request because as of now I think only file contents can be copied. Since the Spotlight comments and body of rtfs are used differently by users, I think it also makes sense to have the option to copy either.
At least for reading and for copyng all to another file, because the view is not editable, Show details could be the only place in DT with a comfortable contiguous view of files content.
I hope this makes sense!
