Some comments:
(1) Currently it needs to be run from the directory where it's
downloaded, even after a "python3 setup.py install". When run from
other directory, it bails with

Traceback (most recent call last):
  File "/usr/local/bin/btrfs-gui", line 5, in <module>
    btrfsgui.main.main()
  File "/usr/local/lib/python3.2/dist-packages/btrfsgui/main.py", line
24, in main
    subproc =3D init_root_process(options)
  File "/usr/local/lib/python3.2/dist-packages/btrfsgui/sudo.py", line
31, in init_root_process
    stdin=3Dsubprocess.PIPE, stdout=3Dsubprocess.PIPE)
  File "/usr/lib/python3.2/subprocess.py", line 736, in __init__
    restore_signals, start_new_session)
  File "/usr/lib/python3.2/subprocess.py", line 1330, in _execute_child
    raise child_exception_type(errno_num, err_msg)
OSError: [Errno 2] No such file or directory: './btrfs-gui-helper'

Is this intentional?

(2) When showing space usage for a single-device FS, selecting "Show
unallocated space as raw space", why is the top and bottom graph
different? Shouldn't it be the same, since there's only one device?

(3) Not directly related to btrfs-gui, but I've been wondering what's
the correct way to SHOW the current default subvolume?
