Currently it’s not possible to unmount images from within Vineyard (silly, I know) but you can do it from the terminal by running “fusermount -uz /mount/point” – you can get the mount point by just running “mount” and check the list.
I can’t disable the devices showing up on the desktop in general, but unmount will come, don’t worry.
Thanks for writing.
I particularly appreciate the hassle-free ISO image mounting, got a question about that: is it possible (or would it be in the future) to disable ISO devices so that they don’t show on the desktop? I have some that I’d like to mount when needed, but don’t want them to clutter my desktop at all times; and the alternative seems to be to delete the entries, and recreate them.
