Well, guy...
Firstly,
I'm sorry for being so late in this topic -- for some reason I just didn't notice it before

Sorry...
As for the request, I think that
a possibility to "rank" special websites must be added into the software, but not the way you suggest, I think it's better to add a separate (editable) column, named smth like "Weight" or "Rank". And I believe this is how we'll do it.
As for you situation, fredm, I think this is a kind of a misfeature, and an improved import procedure (allowing you to import dates as well) must solve this problem.
What do you think, guys? Did I get your questions correctly, and do you think the solutions offered here whould be the best possible ones? Or do you have better alternatives?
