  • expanded by default if number of attachments is no more than 3
  • collapsed by default if number of attachments is more than 3
• Card shows a list of attachments with list items having:
  • file type icon, same as in OpenCloud Drive (no thumbnails, yet!)
  • file name (must be truncated when name is too long)
