The white- or blacklist of the "Cookie Filtering" dialog could be sorted, so that it's easier to find a certain entry. * alphabetically (abc.com, def.com, ghi.abc.com) * hierarchical, alpabetical (abc.com, --ghi.abc.com, def.com) I'd prefer the second variant, where each level of domains is a new sorting key/level. BTW: When already touching that dialog, double clicking/pressing F2 to rename/edit an entry would be a nice comfort feature :)
