* - status bar support.
*
- * - preset selection. Should be reasonably simple: just a matter
- * of dynamically frobbing the menu bar.
- *
* - configurability. Will no doubt involve learning all about the
* dialog control side of Cocoa.
*
* _worst_ this should involve a new Halibut back end, but I
* think help is HTML round here anyway so perhaps we can work
* with what we already have.
+ *
+ * - Can we arrange for a pop-up menu from the Dock icon which
+ * launches specific games, perhaps?
+ *
+ * Grotty implementation details that could probably be improved:
+ *
+ * - I am _utterly_ unconvinced that NSImageView was the right way
+ * to go about having a window with a reliable backing store! It
+ * just doesn't feel right; NSImageView is a _control_. Is there
+ * a simpler way?
+ *
+ * - Resizing is currently very bad; rather than bother to work
+ * out how to resize the NSImageView, I just splatter and
+ * recreate it.
