I am 99% sure this used to work properly and is a new bug.
If you have a split transaction which includes multiple transfers, it used to show the "Go to the other side" link for all of the transfer rows.
Now, it only shows for the first one. Or sometimes the second one. And I even see some old transactions which don't show for any!
This makes it more difficult to debug when splits and transfers get weird. And in general seems like a UX downgrade. I hope you guys can fix this! Thanks!
