List menus down side - all look the same

There needs better differentiation on the side bar menu (apart from ability to sort folders) - the side bar headers are damn confusing - book marks, lists, tags.

I am forever pressing the links in the bookmarks thinking they are a file.

Have the ability to put a background on these folder headers or some better way to separate them. Maybe keep the bookmarks and tags in another area eg. bottom, files top or something. They don't need to be cluttering the side bar if rarely used. Perhaps a searchable bar, where you search for them and as you type, the bookmark or tag appears in another search box at the top of the work area.
