Ah, but the issue isn't you knowing which 'item' you're dealing with. It's that the IDE doesn't know, and therefore can't jump you there instantly if you ask it to.
Instead, you have to open the file in question and go find the method using one of the fiddly text-based methods that the article mentions.
So no, we're in agreement that the entire codebase belongs in your head. It's just nice to have your IDE also have the entire codebase in its head, in the actual configuration it is, rather than just knowing about a bunch of text files containing words that have no meaning to it.
>knowing that my codebase has half a dozen classes that expose a .hide member. I hesitate even to ctrl+click on it in this editor, because I know it'll either do nothing or take me to the wrong definition.
to mean you were relying on your IDE to tell you which .hide() method you were calling.
As others have pointed out elsewhere, I think giving that functionality to ST2 would push it too far into the realm of IDE.
