I don't really like the category title "Recommended add-ons".
Exactly who recommended these and for what?
The implication is that it is recommended that everyone install these. If that is the case they should just be included in the product.
If that is not the case, then recommended is NOT the correct word here.
Also, if an add-on is NOT recommended then is that supposed to mean that I should not install it?
Perhaps "Suggested add-ons" or "Popular add-ons" would be better choices for the title.
