Suppose I'm doing a Sync/Equalise. When I hit preview, Toucan highlights files which are about to be copied in blue color. But if such file is inside a directory, the directory is not highlighted. So there is no way to tell by looking at the directory, whether it will contain changes, without expanding the directory.
I'm requesting to add some kind of highlighting or icon change for directories which are not to be copied by themselves, but which contain files/directories which are to be copied. Same thing for files to be deleted.
