In reply to Blue.

At the moment, I have no plans to add it, but I've given it some thought. Considering that the code would just basically be adding some custom text strings to core WP's cropped image control, I'm not sure the control alone is worth it as a feature.

If I ever did logos, I'd probably make a full feature where theme authors could make a simple add_theme_support() call (like custom header and background) along with custom functions for displaying the logo and such.
