With a lot of folders, the folder icons take up a lot of space in the media library window. It would be great to be able to use a different layout, e.g
. tree view and/or have the folders display on the left side. On my search for similar design issues I found the following plugin https://codecanyon.net/item/wp-real-media-library-media-categories-folders/13155134
which does pretty much exactly what media folder does, just in a different layout which I must admit is nifty.
Maybe something WP Media Folder could incorporate for a next version.
