I don’t know if anyone suggested this already, or even finds this as an issue, but it’s just something I come across when I am editing a certain viewport other than default desktop.
It would be lovely to edit a page in a viewport, say Home page on mobile, and click into another page and it STAY in that mobile viewport. What happens now is that if you click to go to another page, it goes back to default desktop. It’s an extra click but it’s a tedious one.
