I second that notion. I've always been irrationally anti-IDE, but in the past few weeks I've been using Pharo Smalltalk for some personal projects and I've realized how much a good IDE can do for you. You should let your IDE handle trivial issues like directory structure, file formatting, etc.

When I write Smalltalk, I ignore formatting and indentation. I just write code. When I'm done, I hit Command+r and the editor formats everything for me. This is just one of a billion tiny bureaucratic issues that the Pharo environment handles for me.

(Offtopic: makes me wonder why we don't build programming environments from the IDE down instead of building them from the language up. Our current approach doesn't seem to be working very well, IMO.)
