Currently, access to all comments is by clicking on the Tree Overview tab immediately below the tree name. If there are many comments, the user will need to click again on the total comments count at the bottom of the overview page to pull up all comments for the tree.
It would be more handy to have one tab near the tree name that goes directly to the full list of comments. Only one click to access all comments and a scroll bar for lengthy lists. If a number appears on the tab, it should be for the total of unread comments and disappear when read. This would function similarly to the "Messages" count at the top of every page.
