We've noticed that the document title bars now truncate the titles at the end as opposed to around the middle. We preferred the previous approach because it allowed for easy inspection of the file extension. I've looked at the XAML styles you provided with the 2015.1 version and this truncation was done with ActiproSoftware.Windows.Controls.Docking.Primitives.TitleConverter, but this converter does not appear to be available anymore in the new version. If not, then we will need to reimplement similar behavior, which is not a problem, but I just wanted to make sure this the old truncation style is not available as an option (or converter) that I am missing before I add extra code to do it.
Thank you.
