First impressions...
I have done a few dummy ads.
I won't lie I quite like the layout. It's growing on me.
However when placing ads there were a few things that were missing or could be improved in my opinion.
1. When images are inserted for me the image at the top in the listing media box should always be the featured image. In my second ad it is not. I had to go back and delete the one it put in and navigate to the one i wanted and then apply that. Not much of a pain but you have to go back into the ad to do it after posting which would be a pain if it always happens.
2. The Listing Media Box. If after posting you decide you wish to change the display order of the pictures you can't move them. You have to click on the manage media Tab, then click on edit listing at the bottom. To me that is TWO steps too many that you don't need to do.
3. Contact Information / Listing. Website entry has to have http. This is not clear. It should be.
That is it for now. If I notice anything else I shall post.
