Title says it all. During Lumi I‘d really love to have my own Lumi-Tree in the background of my HA if at all possible. Oh the possibilities of all those lovely Lumi-HA‘s!

This used to be obligatory. If you had one, it showed on your HA. Trees weren't a separate thing you could see in your signature. Many users didn't like it. Because trees do change it also slowed down the site.
