Annoying UI bits...
There I attach an image about a quick approach for a cleaner looking on the top frame. I think the icon is too big, and it makes just nothing. There's almost no Mac app with decisions like that, because there are design guidelines and some commons sense of minimalism that tends to clear the interfaces of unnecessary elements like this one.
Also, the Donations appreciated is too stuck to the status, resulting in unbalanced spaces (few distance from the banner at its top, and much from the lower box limit). By removing the icon, the banner can be moved to the right (resulting more regular –most applications tend to place that kind of banners at the right, take TotalFinder in Trial Mode as an example–).
Anyway, I would also like to take the chance to give thanks for such a great extension.
