Aperture has a very flexible approach to the layout of it's working areas, although there are a couple of bits where it could do with improvement. Even better, almost all of it can be changed with keyboard shortcuts.

Aperture is a comparatively ‘deep’ program - there are lots of things you can do in it, and there are often multiple ways of achieving an objective. This means that it can take some time to get to grips with Aperture, especially combined with the virtual organisational structure and virtual images. Anyway, to get to the point, that means there are often a lot of little functions (especially keyboard shortcuts, I love keyboard shortcuts...) that people aren’t aware of, a few of which I’ll list here.
