Would be great if the title tag could be unicode, so you can use emojis.
If you build a map with items around the world it’s useful to use the emoji flags, so you can easily see the country of an item or group.
It is also very helpful, if the groups can have more attributes than just the title.
To describe a group the attributes description and link from items would help if they are on a group too.
The description and the link could be displayed on the info tab.
