Yep, I completely agree.  I noticed this myself recently on my laptop.
Having to open up a thunar window just to eject a flash drive is annoying.

I don't think this last bit is necessary, and calling sync() or fsync()
doesn't necessarily flush dirty buffers to disk (at least on Linux).
Actually, on Linux, there's no way (AFAIK) to guarantee from userspace
that buffers are flushed to disk.  (Not to mention the HW on-disk
buffer, which may not have been flushed.)  So basically this feature is
at best misleading.  The only way to really ensure that data gets
flushed at least out to the hardware is to unmount/eject the volume.

But yeah...  status icon = good idea.
