+ Python
+========
+
+* Receieve menu input while text is scrolling,
+  rather than having to interrupt with spacebar first.
+
+* Make a way to save and load games.
+
+* Make extra hard puzzle generation fast.
+
+* After porting ooStudy into Go,
+  collect data through python. Particularly:
+
+  - Consider fully-inverted puzzles as equivalent.
+
+  - Consider translated toroidal puzzles as equivalent.
+
+  - How many different n by m puzzles are there?
+
+  - What correlations are there between puzzle piece composition
+    and the number of possible solutions?
+
+
+   Go
+========
+
+* Port ooStudy into Go.
+  Implementation should have a bare-bones ooPuzzle with:
+
+  - ooPuzzle.__init__
+
+  - ooPuzzle.set_pieces_from_game_id
+
+  - ooPuzzle.set_pieces_from_edges
+
+  Start with the toroidal implementation,
+  then do the normal boundary,
+  then implement no boundary -- that is,
+    the boundary is not logically parsed at all.
