would be good to have capabilities of dragging and dropping and also copying items instead of the arrows to move files to create a playlist. be able to create sub-playlists and insert them anywhere into the main playlist. instead of using those arrows. they are a little cumbersome. like a block of music videos (hot 10's this week) or promos on top of main content. we're trying the demo and want to purchase for our video page. so far we like most of the features in 4K and PRO versions. All together we're not too familiar with app yet, but looks awesome!!!
