 # BrainBrowser Test Plan
 
 1. Load BrainBrowser by clicking on the chosen minc file.
-
 2. Navigate on all three views (sagittal, coronal and axial). 
-    - Check that coordinates updating while moving cursor. 
-    - Check that slices are updated in the other views correctly 
-        -> if move toward the nose, should also see the nose in the other views
-        -> same for top of the head 
-        -> same for left-right orientation
-
-3. Check that the filename is displayed on top of the control box (below three views)
-
-4. Check coordinates 
-    - Enter world coordinates and check that the cursor moves across the volume. 
-    - Enter voxel coordinates and check that the cursor moves across the volume. 
+    - Check that coordinates updating while moving cursor.
+    - Check that slices are updated in the other views correctly
+        - if move toward the nose, should also see the nose in the other views
+        - same for top of the head
+        - same for left-right orientation
+3. Check that the filename is displayed on top of the control box (below `Sync Volumes` and `Choose Panel Size`)
+4. Check that clicking the filename or the arrow in the header causes the panel to expand and collapse.
+5. Check coordinates
+    - Enter world coordinates and check that the cursor moves across the volume.
+    - Enter voxel coordinates and check that the cursor moves across the volume.
     - Enter 0, 0, 0 as voxel coordinates (should bring the cursor to the bottom left of each view).
-
-5. Check all color maps
-    - Grey (should be that color by default
+6. Check all color maps
+    - Gray (should be that color by default)
     - Spectral
     - Thermal
     - Green
     - Blue
-
-6. Check threshold options
+7. Check threshold options
     - Enter different values in the threshold text boxes
-        -> Check that it changes the intensity of the images.
-        -> Check that the slider is updated. 
-    - Move the min and max button on the slider 
-        -> Check that the intensity changes.
-        -> Check that the values are updated in the text box.
-
-7. Test "View slices" buttons (Sagittal, Coronal and Axial)
-    - Should give a screenshot of all slices within the selected orientation.
-
-8. Close BrainBrowser window
-
-9. Load BrainBrowser by clicking on the "BrainBrowser Volume Viewer" link below the pic.
-    - Repeat 2 to 7 steps.
-
-10. Load BrainBrowser using the "Add panel" checkbox (on the left of the pic) and the “3D only” button (left panel). 
-    - Should display only the selected image(s), no overlay. 
-
-11. Repeat 2 to 7 steps on each displayed volume. 
+        - Check that it changes the intensity of the images.
+        - Check that the slider is updated.
+    - Move the min and max button on the slider
+        - Check that the intensity changes.
+        - Check that the values are updated in the text box.
+8. Click on the “Sync Volumes” button (top of the page)
+    Should update coordinates for all volumes.
+9. Select a different panel size from the `Choose Panel Size` drop-down.
+    Should change the size of the three displayed volumes.
+10. Test `View slices` buttons (Sagittal, Coronal and Axial).
+    Should give a screenshot of all slices within the selected orientation.
+11. Load BrainBrowser using the `Add panel` checkbox (on the left of the pic) and the “3D only” button (left panel).
+    - Should display only the selected image(s), no overlay.
+    - Repeat 2 to 9 steps on each displayed volume.
     - Check that it updates only the appropriate image.
-
-12. Click on the “Sync Volumes” button (top of the page). 
-    - Repeat 2 to 4 on each displayed volume. 
-        -> Should update coordinates and view for all volumes together.
-
-13. Close BrainBrowser window. 
-
-14. Load BrainBrowser using the “Add panel” checkbox (on the left of the pic) and the “3D overlay” button (left panel). 
+12. Load BrainBrowser using the “Add panel” checkbox (on the left of the pic) and the “3D overlay” button (left panel).
     - Should display the selected images plus the overlay.
-
-15. Repeat 2 to 7 steps on each displayed volume. 
+    - Repeat 2 to 9 steps on each displayed volume.
     - Check that it updates only the appropriate image.
-
-16. Click on the “Sync Volumes” button (top of the page). 
-    - Repeat 2 to 4 on each displayed volume. 
-        -> Should update coordinates for all volumes.
-
-17. Test the “Blend” option (text box and slider) on the overlay. 
+13. Test the “Blend” option (text box and slider) on the overlay.
     - Check that it switches display between the different volumes
-    - Check that it updates the slider and text box respectively. 
+    - Check that it updates the slider and text box respectively.
