Exporting folders?

I haven't found this mentioned anywhere (except this old post) but is there a way to export an entire folder and its sub-folders? I'm using v4.0.9

For instance, I have something like this structure

"Some folder" (0 items)
  "Sub-folder 1" (3 items)
  "Sub-folder 2" (0 items)
    "Sub-sub-folder" (4 items)
  "Sub-folder 3" (5 items)

The item count is meant as "directly nested items". I.e. "Some folder" and "Sub-folder 2" don't directly contain any items, only nested folders.

I'd like to export the entirety of "Some folder", but if I select it and attempt to export, I just get an empty file. However, unlike version 3, version 4 now names the exported file "... (0 items and 0 folders)". Version 3 only added "(X items)", but version 4 seems to have (planned, at least) support for exporting folders, given the file naming scheme.

Of course, I had selected a folder, so it shouldn't say zero.

If I select a folder that does have directly nested items (thinking that maybe that'd work), 1Password still insist I'm only exporting X items and zero folders.

In a crazy random happenstance, 1Password crashed while I was writing this post. Heh.

Anyway, is there something I just haven't figured out, or is folder exporting in the works or something?
