Details Section full view

Hey I have an issue with the Details View as I want to display a whole Email throughout the whole width of the section and not just a small collumn as you can see in the screenshot. How can I adjust that or is this not possible yet?

You can control the display width of each field. Go the the edit screen on the right, click “Fields” at the top, find the relevant field and click edit, then adjust the field width to “full”

That should work!
