Before starting the topic, I checked your manual, so, sorry if I missed the solutions for the following issues:
1. Whats the most suitable way to hide “entry-title” and “entry-summary” of the posts for all/one archive pages? I just want to set only featured images as a link to single posts. Maybe you can add this feature into the future GP versions?
2. Is there any way to hide the header container on the specific archive page? (not css display:none;)
