I just recently updated Urban Square, adding Custom Logo support and two new font themes. In the WordPress backend, simply update the theme under Appearance. To see a few new screenshots and updated information, you can go to this theme’s post.
The JGD-Black GTK+3 theme has just seen several updates. The most exciting new update is a new dark variant. Additions also include new borders around CSD windows to allow for resizing. For the latest screenshots, head to the theme page.
