I hope I'm not repeating something I've said before.
Over the past few months people have commented that they miss the ability the Favorites provided in VG to control how often cards are played. I've discovered a way to do this using playlists.
Here is a simple example. Lets say you have a bunch of cards you want to include in a playlist but you like some better than the others.
1. Make separate playlists of the two groups of cards.
2. Clear the playlists tab and copy in the good but not great cards.
3. Now without clearing the playlist tab copy in the great cards TWICE.
4. Save this as a new playlist and it will play the great cards twice as often as the good ones with Random and Repeat both on.
Is twice as often too much? OK, copy the good list twice and the great list three times and the great will play 150% as often as the good.
Love complexity? Have a third playlist of super cards and copy it five time into the 2 + 3 list. Now the super will play 250% as often as the good.
Hope this makes sense and help some of you.
