Its just an idea but...
What about a class view. Using a tree view control with little symbols to display class methods, variables and parent classes etc. You could make it show classes in the open file a bit like how the soubroutines combo box did int the IBasic IDE and it could also display built-in classes so you can drag and drop them into your code.
I understand that this would be something added much later.
Visual Studio and other IDEs have this along with other features, it's nice to be able to see it all there.
It is part of the plan ;)
Good stuff
On the topic of feature requests, I'd like to see something like visual studio has that looks for //TODO: comments and gives you your todo list. It's just a nice handy thing to have when you're thinking "So, what can I do?"
I suppose this could be done with a specialized version of the Find in Files, but searching through the project.
