I'd consider myself an intermediate to advanced wordpress user, and intermediate programmer.
This plugin is so clunky and difficult to use. You have to switch through several tabs and modal windows just to make one player.
Descriptions of sections and buttons is vague. User Interface and Usability Design is terrible and non-existent, respectively.
If you have a playlist on YouTube you want the player to display, HA not gonna happen with this plugin. You have to individually link to every video, fill out meta data, hit save, switch to another tab blah blah etc. etc.
Too much work.
