Can you please let me know how to create an alternate?
You’re using our web-based version, myBalsamiq, right? If so, you can find instructions on proposing alternates here: https://docs.balsamiq.com/mybalsamiq/mockup/#proposing-alternate-versions. In short, on the single mockup page, scroll down to the comments area and click the “Propose Alternate Version…” button.
Hope this helps,
There it is! Thanks very much, Leon
