In addition to the current tooltip, which shows color legend, if user holds the Shift key during hovering we show another tooltip which contains a table of contents for the piece under the moue cursor. The table lists file sizes and names. If the cursor points to a part of a file which spans several pieces, those pieces are highlighted.
