This is a response to volume 3, Tomás Card Number 6 ("I'm ashamed to admit it...")...
Great idea. From now on, the icon in the upper right-hand corner of voice cards will link to the appropriate card in the Member List stack.
You mention adding a Go Recent (do you mean Go Back) button and address field to the More Info card. Of course the Info card is already linked to the address card, but perhaps it wouldn't hurt to have a little redundancy. Go Back buttons can be a bit tricky (they sometimes zip off to places you don't expect) but I'll think of something. Actually, I am already planning to re-design the Member List stack and I'll try to incorporate your idea into the new design (I'm open to other suggestions as well!).
Meanwhile, use the tilde (~) key to move back down the HyperCard trail or type Command R to summon the recent card window.
