Thanks for adding the zoom-hiding hotkey! With that, plus the tip you gave me in April about the maximize hotkey, HoverZoom now does everything I need it to do! Accordingly, I have bumped my review up to a full 5 stars.
I can't say it often enough: developers who are responsive to their users' needs are awesome.
Now that HoverZoom is perfect ;-) , let me put a bug in your ear for something that might make it even more perfect. Currently, you can set HZ to zoom only while a hotkey is pressed OR zoom unless a hotkey is pressed. Would it be difficult to add the ability to have whatever default one has chosen be reversed on a particular site?
For instance, suppose I have it set to always zoom on hover, and hide the zoom when I press Command. What I'm asking about would let me set HZ to reverse it for, say, google.com, so that on that domain, the zoom would be hidden unless I pressed Command, but on other domains it would still zoom unless I pressed Command.
I don't know how difficult that would be to add. But I'd be willing to pay for that additional feature. Even without it, though, HoverZoom is still pretty much perfect, and I will continue to sing its praises and recommend it everywhere.
