Ba-da-bing, ba-da-boom!
The contrast between this jet-propelled 21st-century system and the old manual methods is like night and day. This took about 12 seconds once I had my swap-centric Wish List set up. The visual feedback is great - using it is an active pleasure.
(And for some reason it has the effect of positive feedback. Clicking, I want to click more. Stimulating!)
I don't know why my first few clicks on the "treasure chest" did not "take" - clicking much SLOWER worked fine. (DOWN ... pause ... UP). Like Tom Clancy's description of desert tortoise behavior in 'Debt of Honor').
I assume that was just my PC being cranky. It has been VERY slow lately. I wouldn't think that my Web browser could be aware of how much code Dave is running behind each "click".
