         - Fixed transport shortcuts not working in some windows or situations. (Tim)
           Added event->ignore to PartCanvas::keyPress. Added setFocusPolicy() to WaveView, Master.
           Added (canvas or view)->setFocus() to WaveEdit, MasterEdit. Test OK.
+        - Fixed rack drag'n drop. Added individual tooltips for effects since the astrip might
+          be too narrow. (Orcan)
