In Studio, the "show UDP definition" tool is fantastic, I use it ten times a day.
I have a couple suggestions:
Could there be a mode where the list is sorted purely by name, not grouped by type? Usually I am looking for a name, and it is not obvious whether I am looking at a function call or a subroutine call. And what does it matter? When I am looking for the definition of DoSomethingGreat() that's all I know. But because the two types are separate, I must look in two places.
And, could labels be added to the list? Some of us troglodytes still use them in certain circumstances (I'm seeking professional help). They may as well be mixed in to the same alphabetical list, for the same reason as above.
Gotta keep that suggestion box full! (laugh)
