The new categories tabs for smilies are a great addition, making it easy to organise smilies and find ones to use. However, it does now mean that to see all of the smilies that are available you have to click on several tabs to do this, or alternatively not use category tabs at all. I'd like to suggest an "All" tab for smilies (which could be optional in the ACP). If used, all smilies would appear here as well as in their assigned categories. This would allow users to have an overview of all of the smilies available to them as well as an easy way to find smilies via their associated categories.
