Nobody wants to start from 0 again. I realize that and I didn't want to rebuild everything manually either.
My laziness becomes your gain, because OF COURSE there is a relocation helper. It already exists for the earlier version of the Callers Caddy. I have used it.
But I know that other square dance caller music management tools are also used out there.
On my list so far:
1️⃣: Callers Caddy (old) – ✅
2️⃣: SQView > next
3️⃣: SD Player V2.0 by Keith Rubow (www.krubow.com).
Comment on this post with the tool you use. And then I'll check if I can create a moving assistant for it as well.
