On higher level nodes of our site we have a utility nav with only 3 links: "sign in", "register", and "browse". The text labels for these actions are too long to keep fully visible at screen sizes 480px and under so we'll be using media queries to render them as icons. Normally we would simply collapse into the 3-bar menu toggle BUT some of these screens will also have a local nav with many links that we will be treating in that manner -- so we don't want to render two 3-bar menu icons. Instead, we'd like to do something like show a user profile icon for the sign-in/register link and something for "browse" (whose label at above 480px is "Browse by Discipline").
Maybe we need to rethink this approach but we were hoping to somehow represent "browse" but have come up with nothing satisfactory. A magnifying glass reads too strongly as "search" and the old binoculars seems awfully lame.
Any ideas or examples in the wild? All suggestions appreciated!
