I tend to have DTTG open as a narrow window on my iPad alongside another app that I am working in. I am using stage manager on ipadOS 26. To reproduce the behaviour I am asking about, open the Apple Books app and resize it to take about 2/3 of the screen. Add a DEVONthink To Go window and resize that to fit the remaining third.
DTTG then rearranges its controls to look like on a narrow phone screen. Now do a search and open an item from the search result listing. Close the item again. Now, how do I leave the result set listing and return to the Inbox? There seem to be no controls for that, and I don’t know of any gestures…
