I'll comment on one of your points here, the key map editor. This is a 
wanted feature but it keeps getting pushed further and further  down the 
todo list. I have no idea how this would work. It would have to be able to 
edit existing keys as well as assign functions to new ones. When editing a 
key the editor would have to allow multiple functions to be assigned and the 
order of those functions to be changed. Where required it would have to 
allow function parameters to be entered.
Does anyone want to have a go at coding something like this? Even some kind 
of prototype on the pc could be useful for testing usability.
