Toggling pages in opera:discards does absolutely nothing. The setting is buggered and won't save unless I'm missing some way of doing so. This is ridiculous. I never even heard of snoozing tabs until recently and I don't like it. I'd much prefer a very user-end simple "turn all tab snoozing on/turn all tab snoozing off." It is beyond the pale that one should have to toggle it per browser tab rather than just turning it on or off.
It would be even better to do both so we as individuals can choose which method we wish to use.
