This is a handy tool, I had often wanted to wort my media files differently to the standard / limited WordPress way of; 1) Either everything in the uploads folder or 2) Media files in folders sorted by dates.
The whole thing works really well.
I do notice a slight lag in speed when inserting media files into posts, now there’s an extra step involved in looking for media files as you have to select the correct folder first and then the file, but in the long run it saves time by being able to locate images more quickly.
The developer responds quickly to feedback.
