All

add second rules list that allows dupes ignore to be ignored up to #?=
- i.e. the page action is not shown
change dropdown for #?= to slider to show relative strictness

Popup

BUG if close setting is true, tabs are not closing
on popup if close setting is not the default display second checkbox prompting to save as new default (action saved on click or on check?)
collapse rules section of popup by default
- e.g. open when clicking on a link to the effect of "Automatically close urls matching this..."
