 # Todo
 
-## Todo Now
-* Make a GUI. One approach is to render individual icons with diagrams using the
-Cairo or GTK backend. The rendering would be in a separate process so that
-interacting and dragging nodes is not slowed down by rendering.
+## GUI Todo Now
+* Refactor and clean up GUI (gui/Main.hs).
+* Add history and undo [Bug #12](https://github.com/rgleichman/glance/issues/12)
+
+## Non-GUI Todo Now
 * Redesign case icon to avoid non-locality.
 * Move @ pattern circles so that they are on the same side as the variables.
 * Add command line flags for color style, embedding, and whether to draw arrowheads.
