On a sidenote, you are encouraged to post your suggestions and feedback on the forum since I am planning another release with a long feature request list that I haven't had the time to investigate.
UPDATE: It seems messers were looking for the Translucent Dashboard option and weren't able to find it. That's because it has been replaced by a new option which makes the conversation window's top toolbar like that of the contact list, which I thought would be more fit for the new 8.5 GUI. Check the screenshot on the right.
