Oh, you're most welcome; please share it with everybody you like. :-) If you're running Chrome (or Opera), it's handy to use it in extension form, to get all the updates and bug fixes rolling in effortlessly, by the way (I think I've almost made up the time it took me to extensionize it, just from not having to keep my browsers in sync with updates :-).
