I love your themes, so I always play around with them, and I found a very small comestic issue with Fluida.
The breadcrumbs disappear under the menu if your site width isn’t wide enough to hold all your menu items. Obviously, it’s an easy fix by expanding the width, but I thought maybe something could be done in a future release so the breadcrumbs are still visible if, for whatever reason, someone is set on having their site at X width.
