Would like to have a second pin to mark columns with a different pin color

This is not worth the effort for me personally. If some one else wants to implement it, I will be happy to supply any needed guidance. If so, re-open the ticket and we can discuss it.

I won't do different colored pins but instead will permit you to mark items with text, which is what the find duplicates plugin does.

With that, everything needed already exists to use the mark text to add column icons and colors, to search for specific text, to put the text in a composite column, and with such a composite column to sort by the text.

Here is a sample column icon template that displays icons for books marked with different values. :)

program:
 if is_marked() then
  m = is_marked();
  first_non_empty(
   if 'reading_list_send_to_device' in m then 'sync.png' fi,
   if 'reading_list_to_be_read' in m then 'list.png' fi,
   contains(m, "search_results", 'search.png', ''),
   if m then 'marked.png' fi
   )
 fi

I think you might have missed the point of using the "pin" feature. I just
wanted to be able to go into the tags browser and click on a tag from one
column and then a tag in another column and compare the results against
each other. What you are suggesting is a lot more than what I need. The
pin feature is perfect, but you can only use one pin in one color. The
need for two pins and two colors is there, but what you are suggesting is a
lot more work than I was hoping for.

Thanks anyway.

Compare them for what? If you want to see books that have one tag nut
not another, you can do so by searching for

tag:A and not tag:B

@Robin: Kovid improved what I did by using different colored pins for different text marks. When you mark a book with some text, calibre chooses a color. I think there are 5 colors available.

You can think of setting a text mark as choosing a different color pin, which is what I think you were asking for. I expect you would assign a shortcut to the new action "Mark books with text label".
