+MISCELLANEOUS
+=============
+
 Integrate low-level X11 graphics, replace all low-level driver code in
 libgraph. All the high-level graphics routines are in place.
 
-Make data file formats cross-platform compatible
+Make SDF file format cross-platform compatible
 
 Integrate audio drivers into libcio -- used for the interactive CT display.
 
+PROPOSED MENU STRUCTURE
+=======================
+File
+  New
+    Phantom
+  Open
+    SDF
+
+Process
+  Simulate CT process (active only when phantom outline shown)
+  Rasterize Phantom (active only when phantom outline shown)
+  Reconstruct CT data (active only when raysum data is shown)
+
+Filter
+  (Various single and dual image transformations)
+
+Compare
+  Compare 2 images
+    2D grayscale subtraction
+    1D column plots
+  Single Image statistics
+
+PROPOSED HDF FILE FORMAT
+========================
+
+If the HDF library is compiled into CTSim, it will be used for the
+raysum and image files.
