I didn't like the idea of a queen on one board capturing the king on another board as her first move. And then I tried this rule and thought it created really fun counterplay when you're trying to capture a piece someone else is controlling, since you can move to a new board to be safe (and can lay traps this way).
I'm sorry you don't like that decision! But I think that I stand by it.

If you did want to experiment with supporting cross-board captures, an alternate way to address that could be by rotating the board 180° every other row, so that white pieces have other white pieces behind their home rank.
