Preferences ==> Tweaks ==> content_server_will_display
Code:
#: Set custom metadata fields that the content server will or will not display.
# ID: content_server_will_display
# content_server_will_display is a list of custom fields to be displayed.
# content_server_wont_display is a list of custom fields not to be displayed.
# wont_display has priority over will_display.
# The special value '*' means all custom fields. The value [] means no entries.
# Defaults:
# content_server_will_display = ['*']
# content_server_wont_display = []
# Examples:
# To display only the custom fields #mytags and #genre:
# content_server_will_display = ['#mytags', '#genre']
# content_server_wont_display = []
# To display all fields except #mycomments:
# content_server_will_display = ['*']
# content_server_wont_display['#mycomments']
