For sure, it can definitely be described as "quirky". My initial reaction was much the same as yours. That said, once I tried copying/moving files around, I was sold on the 2-column layout. I recently got a new phone, which meant moving my custom ringtones and notification sounds to their correct locations. With Google Drive I downloaded them, then using X-Plore I moved them to the ~/Notifications and ~/Ringtones folders. That was fairly easy to do - you find the destination in the right hand column, then swipe back to the left column, select the files for moving, then choose copy/move. It's kind of like the column mode in Finder on OS X, which I really wish I had on Windows 10.
