Like all silly ideas, this one got a bit out of hand, and seems to
have turned into something vaguely useful. I'm therefore pleased to
announce the first major public release of btrfs-gui[1]: a point-and-
click tool for managing btrfs filesystems.
The tool currently can scan for and list btrfs filesystems and the
volumes they live on. It can show the allocation and usage of data in
a selected filesystem, categorised by use, replication, and device. It
can show and manipulate subvolumes and snapshots: creation, deletion,
and setting the default. For those with servers to manage, it also has
the ability to ssh into a remote machine, and manage its filesystems
remotely (so you don't have to have X installed on your servers just
to use btrfs-gui on them).

Unless the traffic gets too high-volume, or unless someone
important objects, I'm going to suggest that bug reports should go to
this list for now (cc'd me, if you like). Note that this isn't an
"offical" btrfs project -- it's just something I knocked together on
my own.
I seem to have stumbled upon a bug.
During install, Ubuntu gives the user the option to use btrfs as the
root filesystem. It automatically creates two subvolumes, @ (for /) and
@home (for /home, only if no other partition is used for /home), like this:
mount | grep btrfs
/dev/sda6 on / type btrfs (rw,subvol=@)
/dev/sda6 on /home type btrfs (rw,subvol=@home)
/dev/sda6 on
/tmp/btrfs-gui-kl6zx1/12624/eba4f1e9-5b55-4e14-abb8-5a3cf3625c56 type
btrfs (rw,subvolid=0)
When gtrfs-gui scans for filesystems, it gives the error
Root helper exception: b'@' is not JSON serializable
This is the relevant console output:
Helper: found label None, UUID eba4f1e9-5b55-4e14-abb8-5a3cf3625c56
