+ </p>
+ <p>Since Jalview 2.11.1, sequence features displayed in either CDS
+ or Protein can be shown as 'Virtual Features' mapped onto the other
+ view. Features describing non-synonymous genomic sequence variation
+ in coding regions are dynamically translated when shown in the
+ protein view.</p>
+ <p>The display of virtual features and whether they are rendered
+ below or above features local to the aligned sequences is controlled
+ by a check box shown in the view's Sequence Feature Settings dialog
+ box. For convenience, Protein and CDS feature settings for a linked
+ CDS/Protein view are shown as tabs in a single dialog box, allowing
+ easy access to display and filter settings for each view.</p>

+ settings tabs and corresponding views showing 'Virtual Features'

+ <p>
+ When virtual features are enabled, they are also shown on any linked
+ 3D structure views when 'Colour by Sequence' is enabled, and
+ exported as GFF and Jalview Features files (mapped to their
+ associated virtual coordinates). Both the original and the mapped
+ locations are also included in <a href="seqfeaturereport.html">Sequence
+ Feature Reports</a>.
