I thought so too -- but it turns out it didn't. I just remembered, there's a new smaller size of iPad Pro. DTLow, judging by the size of your keys, you must have the 10.5 inch iPad Pro as opposed to the larger original iPad Pro (which I have). I guess you could use an app like AZKeys to forcibly add a tab key, but again, this shouldn't be necessary.
I also messaged Evernote Support again to inquire if they had any ETA about this ongoing usability issue. The response:
"At the moment I don't have any updates or the ETA on implementing this feature. While we can’t commit to getting all feature requests into the product, we do rely on our community to tell us what they’d like to see in the future. "
Considering how many other suggestions in this forum have more upvotes and it's been such a long time, I am not feeling optimistic. At least this one is still on the first page. I'll ask some Evernote-using friends to consider upvoting this.
