That is an image of the search tab. Just remember please look at the program prior to asking questions. It is a very easy to understand and user friendly interface.
All I can stress is that discontinued and outdated addons or libraries will not show up. You should not install them unless you want to take on the responsibility of troubleshooting them yourself without help from others and you should expect to know how to change or update the mod. If not then again, do not install outdated or discontinued addons or libraries.
