Just listened to the first podcast. Keep talking about the marketplace; completely agree with everything you guys said.
Will be listening tomorrow at 1pm.
Our Adora theme has a menu under-neath the slider. I’ve seen a few other themes like this as well . Alternatlively you could hire somebody to move the menu on any theme for you. The cost on that modification should be small.
Check out our Momento theme for that functionality. Also, try checking out the photography category as there are a few themes with that feature.
Keep up the good work. I love checking out your new themes.
I would send support an e-mail and let them know. I believe a few authors have had items hidden until they make certain updates. Working on the current version of WordPress should be a requirement.
Also, take a look at your hosting provider reviews. Some hosting providers like GoDaddy are known for being horrible at load times. Your WordPress Theme should be running super fast.
