This is a great suggestion. Thank you for your feedback. We have added a comprehensive search to our recently released VI Package Manager Beta browser app that allows you to search by terms in nearly all textual fields in the package including the package description. We currently support whole words only but have plans to improve the search to include partial search terms as well. Please visit the browser app using the link below and provide feedback if this approach addresses your use case.
