I've reviewed 41 package posts and I don't see any whining about package workflow. I"ve been keeping my packages out of SDDM for the most part but dependencies are requiring that some migrate to SDDM.
I create a simple package:
CREATE OR REPLACE PACKAGE "Package1" AS
CREATE OR REPLACE PACKAGE BODY "Package1" AS
procedure a is begin null; end;
My first complaint is the the tab names are not distinguished -- they are both Package1.
My second complaint is that a DDL export is empty (which I expected) but this leaves the possibility of exports being out of sync with what is in the panes. Furthermore, there is no explicit save -- I had to close the tabs to be prompted for the save. Of course saving the physical model does save mods to the packages.
