First, I noticed that the tooltip text that comes up next to the advanced toolbar hide/show button says to click on "ctrl-b"; that's not correct, of course, it's actually "ctrl-v". I'm on a Mac, so maybe it's correct on Windows, but I'd appreciate it if you'd fix it on the Mac too.
Second, that button comes up on the second, hidden level of the toolbar. That seems odd; I mean, why make it an Easter Egg? That hide/show button should be on the always-showing level of the toolbar, I think.
Finally, as some others have suggested in other places, it would be great if there were some user preference to make the advanced toolbar show all the time.
Thanks for a great product!
