For example: Home > Field Education > Field Personnel, Search When the results of a search are displayed, the leftmost column contains checkboxes. The column header for this leftmost column also contains a checkbox. The purpose and usefulness of this column-header checkbox is not identified. For users not familiar with this box's "select all" capability, it would be beneficial if the box had the words, "Select All" to the right of it.
9/3/14 update: At the very least, when the column-header-situated checkbox is hovered over, the words "select all" or something even more clear should appear. (Moving from "Not an Issue" to "Open.") - ljr
