The Next Unread Button (top of any wave) has the same icon with the nearby Next Button. Instead, it should have a unique icon, like the Recent Button has. I suggest to somehow combine the down arrow of the Next Button with the closed eye of the Unread Button. Alternatively, an asterisk ('*') could serve the same purpose, either combined with a down arrow or alone (after all, the first unread blip may be located higher in the wave than the current location of the user). After giving to the Next Unread Button its unique icon, it should turn gray when there is no unread blip left in the wave (now it's permanently green). Finally, the tool-tip of the Next Unread Button should change from "Next Unread" to "Next Unread (SPACE)" or maybe "First Unread (SPACE)". In a side-node, the tool-tips of that group of buttons could be more verbose to fully explain their action, maybe by including the word 'blip' in them.
