It would be useful if You could set the duration of an effect in the slideshow.

Especially when You have a slideshow in the header, it would be very nice to ex. set the duration to a long time for fading in/out.

This would give the site a more cool and not so disturbing look.

Why in the h... is it, that You are not able to add text in the header slideshow ?

The last one was both an idea and a comment.
