I will also try the Alt-dbl-click "feature". And yes, as it happens, I do have a degree as a programmer, and will take a look at the link you mention.

Also, I'm happy to donate if a product meets my needs. I'm still evaluating whether this does that or not. I *really* like having the much smaller profile that your extension offers. Its much cleaner than Sidewise. I will probably make a suggestion or two once I've gotten past the "new user" phase. Although it is taking me a bit to get used to having to dbl-click to get the effect I want... once I'm past that, I suspect it will be close to perfect.

Thank you for your attention.

Ah, that is a good point. It hadn't occurred to me that it might be Chrome opening the windows, and not not TO. I will try that. And I'm sorry if I got a bit snippy there. I had been at work for 18 hours and was pretty tired. I shouldn't have taken that out on you.
