Apart from the obvious "(When) are they coming?", I've a few more to ask, if the answers are known.
How will they work? Built into the game's code? Run from an external file?
Will they still be editable by the original author? Other people?
Can we make them unlockable, such as by completing a cusom level pack?
Will we be able to edit the game's UI to make them easier to use? Rallypoints took a while to set up because I needed to make a drawn button to activate them.
-- Alex, Rudolph - we need to be able to edit the UI, perhaps even just by making buttons and, even better, customisable sliders (start, finish, what they affect, position) I'll post more about my thoughts on this in a moment. I've got an idea that doesn't seem too nasty to implement at your end, but I don't know much about C#.
