Thanks, I'm aware of this, but this is a bit different.. Would be great to get ability to compare against something like anchors.defaultLeft (https://link.getmailspring.com/link/1523014719.local-23d3901e-507d-v1.2.1-7e7447b6@getmailspring.com/0?redirect=anchors.defaultLeft&recipient=aW50ZXJlc3RAcXQtcHJvamVjdC5vcmc%3D) or anchors.NoAnchor (https://link.getmailspring.com/link/1523014719.local-23d3901e-507d-v1.2.1-7e7447b6@getmailspring.com/1?redirect=anchors.NoAnchor&recipient=aW50ZXJlc3RAcXQtcHJvamVjdC5vcmc%3D) in future.

Of course introducing change handler allows to track moment of anchoring (although still no way to track un-anchoring), but this is a bit ugly and not 'Qt-way'.
