Is adding a new layout now the only command to view existing layouts? Am I missing something?
I’m looking into this now. I’m not sure what happened. In the meantime, you can use the Layouts… button in the upper right-hand corner of the viewports area.
I’m still not sure what happened here. I need to look at this with Marlin. Logged in MR-3205.
We have fixed the bug above and plan to publish it in an upcoming 5.4.1 update. We have a number of other bugs to address and fix before that update is published. Sorry for the inconvenience.
