Hi Dean, the timing looks like it *should* be deployed to production around June 3 - 5, prior to *most* end users getting the Summer '19 release. (Only the instances na45 and na45 go before that.) All subject to change/ safe harbor.
If anyone has particular concerns please email me with your org ID.
[Edited June 6, 2019: Updated to add a backend option.]
Here is the current status:
* Due to customer feedback we decided to make the utility bar remain left-aligned by *default* in Summer '19. You should see this in all orgs as of June 6, 2019.
* Due to additional customer feedback, we will be releasing a backend option by June 30, 2019 where I can make the utility bar right-aligned in your org (safe harbor). If you would like that configuration, please send me your org ID(s) via email and I'll flip the switch when it's available. We can coordinate details via email. (Note: This configuration will apply to all apps in the org.)
Exposing this option in the app's Setup is planned for a future release (safe harbor). (If you participate in the org-level backend option there will be a transition plan so you can use the app-level Setup option when it's available in a future release.)
