Seems like such a silly thing to ask, as I'm sure it's right there in front of me somewhere… but I can't figure out how to delete a remix set. In TP3, you could right-click on it in the browser tree. Now in TP4 you can't.
Silly me… the solution is to right click on the remix sets shown in the browser, after selecting "all remix sets" folder in the browser tree. A little wonky, but AOK.
Something's wrong… for that matter, I can't even LOAD my remix sets into a deck (even after clicking the deck letter (A, B, C, D) and changing it to "Remix Deck"…
Nothing happens when I right-click on a Remix Set… there is no context menu at all
