I came across Media Library Assistant when I was in desperate need of a search fix for the media section in WordPress.
This came up when images were being optimized. Once an image is optimized you can no longer search for it via its file name, but name now given to it. If a client or ever yourself were to delete that name, or say a designer came into to edit images and knew them by their file names, they would no longer be able to search for them accurately.
Media Library Assistant solves all of that! You can search by slug/title/file name and more!
I am using it across all of my sites. In addition to being so good it should be part of the WordPress core. The support on this plugin is better than most premium plugins.
Big shout out to David Lingren and his great plugin.
Dont take my word for it, try it yourself. You will not regret it.
