at the first level, in the folder tree, DOpus can show things like Libraries, or the Desktop. (Within the Desktop, DOpus can even optionally also show the virtual userfolder.)
However, I found no way to display a randomly chosen folder at a handy place, and have its subfolders be expandable in the folder tree. Neither does it work with quick access, nor with favorites, let alone displaying a user-chosen folder at first level or under the desktop item.
On the other hand I do see "Mac Files" and OneDrive in a handy place, on the same level as Recycling Bin and "This PC". I don't know how Parallels managed to place it there; it's obviously a virtual folder that corresponds to the Mac Harddrive accesed via network on the same MacBook. Basically what I would want is that Mac Desktop and Mac Downloads appear besides OneDrive/This PC etc., or in a similarly hand place, and ideally not using junctions or symlinks unless that's necessary.
Also I don't understand why quick access/favorite folders are not expandable in the tree?
Thanks for help!
