I would like to be able to take the current open procedure/package/function either opened from a database or a file and compare to the current database or any other database all within the Editor. I currently have this feature in PL/SQL Developer and I use it many times throughout the day. Often people give me a bunch of files to review and I like to open them all up and then for each one I do a compare to my database to review changes. Or when I change something I like to review my changes before I compile.
Right-Click in the Editor, choose “Compare to”. Your options are database object, file, or another editor tab.
