Can I deactivate the two column layout in ipad app?


In the nextcloud app for ipad, there is a kind of a two column layout. The file tree on the left, the file content of the selected file on the right.
For me this functionality is very unpractical, because most filenames couldn’t be read completly, because the space of the left column is to small. I would prefer to use the space to see the whole filenames instead of having a content view on the same screen.

Is there a way to deactivate this two column layout, so the app would work on ipad the same way like it is on iphone?
Or is there another way to see the whole filenames in the left column?
