+G0WFV's HD44780 todo list ...
+
+As I only have a 2x16 screen at the moment, development has been done based
+on this size screen.
+
+Some additions I can translate to the other size screens without connecting
+the physical screen (and I will do eventually once I get the code working 
+for the 2x16!)  I am however getting some 4x16 screens to play with so 
+expect more reliable progress in this area!
+
+Here's a list of things I need to accomplish in the near future ...
+
+- Propagate non-duplex (DVMega) screen usage changes to other size screens
+  as appropriate.
+
+- Propagate custom characters for rf and ip sources to other screens 
+  Currently only states "R" or "N" for RF or network traffic, which is nice
+  but there are now custom characters for this!
