(does the nautilus gui disappear if timeslider is disabled - if so, that sounds wrong to me)
This could be my misunderstanding of the parts of this. When I disabled the auto-snapshot resulted in timeslider being disabled too. So what does the timeslider service do?

The service checks for/sets the property on service start on any pools that appear on the system: in effect, this means that removable media won't be snapshotted by default until the service refreshes. So only media that were inserted and mounted at boot would get snapshotted by default (unless the property was already set on those pools to tell the service to leave them alone)btw. I've a changset checked in to have the service not take snapshots of swap & dump devices, which was broken in nv_100/101. There's a known bug about the service breaking for datasets with spaces in their names, I've got an ugly fix, but want to have a go at doing a better job of it.
I'd really like to be able to turn it off by default globally and then turn it on in a controlled fashion. If you take snapshots of file systems that are targets of zfs send | zfs receive it will prevent the back ups working at all and require a lot of manual effort to recover.
