HDView has two viewer-selectable options--the hand tool and the tone mapper.
I just looked at several different HDView panos. I prefer the movement control to be the one that is not the hand tool, but realize that others have different opinions.
So I'd like this tool to be sticky across all panos that I view--that is, make the default for this control be read a cookie stored locally on the local machine that overrides the author's setting of this control.
Not sure about the tone mapper. Each pano is different, so the author's initial setting may be best. But each monitor is different, so it may be better to let the user have a sticky setting for this control also.
