Have you looked at whether PL/Scope information could be used within TOAD? I’d be particularly interested in whether the Used By data could be enhanced to include additional PL/Scope information (if available).
What I’d really like to see on the Used By tab of TOAD is how a package is used by another package (not just that it is). For example, is the reference to a procedure/function call or a package variable perhaps. Would PL/Scope provide us with that detail and could it be easily (and efficiently) added to the Used By result set?
As you can see, I’ve not had a chance to play with it myself so I’m wondering if anyone else has looked at PL/Scope and how we might be able to start enhancing TOAD to take advantage of this additional information.
