Download the icons a server advertises for its groups over the file transfer channel, cache them under the config directory, and draw them as a badge strip on each client's row, right-aligned against the tree's visible edge like the TeamSpeak client does. Groups without a custom icon fall back to the bundled default set. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
