On the page http://catchthemes.com/features/ it clearly states that the features on those pages are included in all themes – the third item is: Featured Slider.
Sub-menus do not work on the secondary location.
If you say that grid is not part of this theme, and slider is not part of this theme, then what are the extra features for the PRO version. I don’t see any.
As for the support forums, I logged in and this is where I was sent when I clicked on support – to the forums. Now you are telling me there are other forums, but there are no links to them. I wasted hours searching your site for support and it all leads to the paid support or this forum. Maybe you need to make your support options clearer, because I am not seeing it anywhere.
