Hi laughingwater,
I'm not entirely sure I understand what you're trying to do, but do you mean you wish to create several playlists that will play various languages in various orders?
e.g.
- Playlist 1 - Afrikaans, Spanish, German
- Playlist 2 - German, Afrikaans, Spanish
- Playlist 3 - Spanish, German, Afrikaans
If this is the behaviour you want to create, you should create three CATEGORIES - a German category, an Afrikaans category, and a Spanish category. Then you should create three PLAYLISTS, as listed above. When selecting items to go in the playlist, you may select entire categories, not just individual words!
With regards to organisation, many of our users like to have a 'Retired' folder where they will drag and drop files that they have already played. You may find this to be helpful!

With regards to moving Categories to Playlists, the functionality of the two are quite different, as Playlists and Categories are entirely different things. However, if you want to have the Category represented in the Playlist section, simply create a Playlist and have the desired Category as the only item in the Playlist, and it will function similarly to the original Category.
Hope that helps,
Shuki
