I believe the answer is:
tabs
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">notebook features</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for tabs that I've seen before include "that are picked up by footers?" , "Marks in computer document" , "It's curtains" , "Bills in restaurants" , "medication" .)
