I create a lot of WordPress templates but most of my work is done in Fireworks not Photoshop (http://www.iconzplanet.com/) for example. So I can include an unflattened PNG file but won’t have a PSD file to include.
Is this a big deal to people who are looking to buy WordPress themes? Will it greatly decrease my number of sales?
Absolutely! And you can always export your PNG to layered PSD
You know what, you’re right. I don’t know why I never thought of that before.
You seriously have given me the most useful advice/suggestion that I have received in the last year.
