Show the count of newly, widely, and limited availability features

To give a better understanding of the shape of the platform, we should have all three counts on top of the start page as filters.

Thanks to Mustafa for the idea and design!

What do you think of adding those filters to the sidebar section instead? That way the sidebar can contain all of the predefined filters and have the existing highlighting when it is active. We could have the logos and the count there too

Sure, that would work too.
