Hi Nikeo. Some bugs for you :-(
There's a bug that seems to show up only on Safari for Mac: From the main page, if you hover over a featured page circle, both moving into the image area and exiting the image area makes the main page title and all the menu items flicker. Somehow, the hover code is working on the menu too.
It doesn't do this in Firefox for Mac, nor Ubuntu.
This effect is visible on demo.themesandco.com, so it's not something I've done to my page that is causing it.
If you click a menu item that has sub-menu items, the sub-menu drops down. If you click it again, the sub-menus hide again. As you move off the menu item, on Firefox a subtle dotted-line appears. Fine so far. If you do the same in Safari, instead of the subtle dotted-line, you get a rather unpleasant light blue border that stays there until you do something else. It might look ok on the blue theme, but on the others it's out of place.
Again, this can be seem on demo.themesandco.com, so it's not something custom on my page.
