When a DEVONthink window is open on a second screen (and there’s no DEVONthink window on the primary screen) then the group selector opens on the second screen.
Especially when adding from Safari (via dragging the selection onto the DEVONthink icon in the dock) its cumbersome to move the mouse to the second screen each time. Already tried window manager yabai to automatically move the group selector to the primary screen but it seems it’s not possible.
Please add an option that opens the group selector on the macOS’ primary screen.
Dragging to the Dock calls services (as the Dock has no useful API in this regard) and since Sonoma this activates the application. Dragging to the Sorter might be an alternative.
