Smaller improvements (2020)

The second half of 2020 brought a collection of smaller fixes and refinements:

• Email notifications improved. The daily summary email now includes discussion and poll edits, not just new content. Notification emails were reorganized for consistency.
• oEmbed replaces iframes. Links to YouTube, Vimeo, and other supported services now embed inline as responsive previews rather than raw iframes.
• Polish language added. The interface is now available in Polish.
• Load more counters. The "Load more" button on threads, group discussions, and member lists now shows how many items remain (e.g., "Load 12 more").
• Audience tweaks. Controls over who can see and participate in threads and polls were refined based on user feedback.
