I had a 15-20 minute quick test of this plugin within hours when it was first released. This is a very good imitation of the Happy Files plugin, well done.

That said, I had an issue and a very important missing functionality:

1. The Issue: Frequently on my localhost ( Xampp, php 7.4, Chrome, WP 6.3.1 ) I end up with the “wait circle thingy” on the screen, when trying to click on a folder, and keeps spinning, until I get out. Disabling the AJAX from the configuration screen does not fix the issue.
2. The missing feature: If you have many authors, and you already have a decent amount of media already, and you are trying to create a folder for each author, the easiest way to do it, is to go to the list screen after you created the folders of course, and from the list screen you can see the authors, you should be able to simply click and drag the images to the folders you want. This works perfectly in Happy Files, but with this plugin this feature is missing. You can only do that in the Gallery (non list screen), which the media authors are not listed unless you click on them, so the task becomes very cumbersome.

I did not leave a review yet, so I can give a chance for the developers to respond to these 2 issues. The ability to have different folder colors is brilliant by the way… Happy Files does not have that !
