I'm using the pro gallery on my site and it's all working fine except for one small niggle. I can't work out how to hide a category from appearing in the recent items section. It's possible to do this on the tinyportal random image block but I can't find a similar function on the main recent items section. The reasoning for doing this is that I have a not suitable for work category for possibly objectionable images and I want to keep this hidden unless a user activey clicks on it. Is it possible through either the default interface or maybe a hack?
