Subject: JAL-2944 ’new view’ and ‘add to view’ button rather than selecting from combo box... 
X-Git-Tag: Release_2_10_4~32^2~4
X-Git-Url: http://source.jalview.org/gitweb/?a=commitdiff_plain;h=f7775ab8e5622ab365c1e178c79ec78a707aad1f;p=jalview.git

JAL-2944 ’new view’ and ‘add to view’ button rather than selecting from combo box to make it easier to successively add structures to existing view (which is the default action when return is pressed)
