 ## Stickman editor (Phase 6 Round 1)
 
 ### Seletion bounding box as well as rotation 'dot' should stay in front of all other objects.
+
 If an object is selected, it's bounding box and rotation dot should be in front of all other objects.
 
 ### Touchpad panning is too slow
-Panning using the touchpad does not moves too slowly.  We need to increase the distance the panning moves through touchpad.

 ### Zooming in/out

+## Stickman editor (Phase 7 Round 1)
+
+### Silhouette starting position (or camera)
+
+When starting the application, the silhouette stickman should be in the center of the view. Right now it starts on the left upper side of the view so the user has to pan over.
+Either move the silhouette or the camera.
+
+### Showing the pose guide
+
+When clicking View->Show Pose Guide the guide toggles on and off, but the text never changes.
+By default the pose is visible so the menu text should say "Hide Pose Guide"
+When it is hidden it should say "Show Pose Guide"
+
+### Guide visibility
+
+The guide and joints should slightly 'ghost' in front of the objects so that the use can see how well the objects are aligned to the joints and limbs.
