There are some useful tools in this package, but I would install only three or four of them. Therefore, I can't see paying for all of them, when most would just gather dust, metaphorically speaking. If they were available for $1 each, say, or in customizable packages of five for $5, it would be a more appealing product. Whether it would be worth the effort for the developer to sell them this way is another question. But it would be more user friendly. No one likes paying for stuff they don't want or don't need.
