Wanted to come back here and say that if Opera prides itself on offering options and customization to its users, it really should follow up on this suggestion, and get rid of the outline of the sidebar when it is disabled. I don't know what sgunhouse meant when he (or she?) said it "isn't disabled." What I would like to see is a totally clean interface when I am on a blank tab or a tab with just the speed dials (with or without wallpapers) that does not show anything that reminds users of how the sidebar is (or could be) there. Great browser otherwise. Thanks, and I hope the developers will follow up.
