First I want to say I really appreciate all the hard work going to the engine, marketplace and everything surrounding this. So great job everyone!
As for the new updates, I think it is a great step forward! Software development is an iterative process. So I would like to add some feedback for a future iteration.
I agree with the feedback above and think with a few small tweaks and additions this will be a really great user experience.
Launcher Marketplace Design Changes
Smaller thumbnails should be considered
Amount of ratings should be shown
Sticky categories (stay on screen while scrolling)
Marketplace Home
Should show featured, popular, and new releases
Marketplace Category
Should have subcategories, tags, or filters
Sorting should be available
