I've been asked and asked so I finally made it. Now your layer names will become class names for each layer that you create in your photoshop design.
This way, you can create readable classes for the DIV's generated for your design. Even the spaces are honored so you can define multiple classes for any layer/DIV. And since layer names don't need to be unique, you can give a number of your layers the same class name so that they can all be easily styled from your CSS.
Of course all the dangerous characters are stripped so just use alpha characters, numerals, your underscores and spaces.
Time to get creative with your CSS and jQuery selectors!

Cheers
Thank you for this feature I have up to this point been renaming all the divs and images manually... Thanks! Oh and hows the new design coming?
Hi Jay - Coming along nicely.
Hi Jay -
Coming along nicely. In fact iterating on it is how I realized how useful those class names are :)
Now you can write external CSS and JS and use the Layer name / class name selectors - and if you modify the PSD and reconvert it all the external CSS and JS selectors still work! So awesome.
Thanks.
