Already since version 4.5 of the Signavio Process Editor, the Beta versions of IE9 could be used for all parts of the Signavio tool. We have put a strong focus on giving full support for the new browser version from day 1.
Our developers also integrated native support for Microsoft's new functionality "Pinned Sites" (see Screenshot). You can drag the Signavio Explorer to the Windows taskbar (Video) and get direct access to some shortcuts through a right click on the Windows task. Additionally, the Look-and-Feel feels more like a Windows application rather than a plain website (e.g. through a distinguished task icon).
