Agree with many other reviewers. This is a smart, well-engineered plugin that introduces functionality that should be included in WordPress core. However, if you upload hundreds of photos to your media library, you currently have to edit each photo individually to connect it to taxonomy terms. That is completely impractical and the only reason this plugin gets only 4 out of 5 stars.
I took it upon myself to create a plugin that adds a bulk update feature for my own projects. I couldn't justify discarding EML, which I otherwise love, solely due to this missing functionality. You're welcome to download it, and use it. It'll get the job done, but I don't intend to support it. So when Enhanced Media Library includes bulk update functionality in the future, I recommend abandoning my band-aid solution and supporting EML.
