Minor Description
The tree view on the admin UI is really helpful to get a view of the znodes in zookeeper. We've found sometimes when troubleshooting issues that this can become quite fickle to use when you scroll down the collections list, select a shard leader znode, and have to scroll back up again to look at the metadata.
This small patch forces the metadata panel to be fixed to the UI, and also forces a horizontal scrollbar for the tree.
Screenshots show the patch applied.
