Can you get rid of all of them?

My preferred UI:

Location bar Sidebar (file tree) | File List

Would be nice if each feature you don't need could be removed from the purchase price. I think the version I want would end up having a negative price tag ;)

That's also another point. I don't want to have to customize a software before it's reasonably usable. I probably don't even know myself how I would like it to be. It's the UX designer's job to make it pretty, not the user's.
