Cozy theme small customization

Hi,
Iv been pleased with how the Cozy Theme presents our archive on an Omeka-S (ver 3.0.1) installation. Our collection consists of 3000+ Items and 50 Item Sets and this theme displays our large Item inventory pretty efficiently.

I’m trying to make a simple customization of the theme: the menu button in Cozy is ambiguous, it looks like

this… menu

How could i change it to something like this? … menu

Thank you, Will
