Site specific settings under "My Filters"

[Elainiwen]

By that I mean creating profiles for filtering which work only while visiting a certain sites or a certain pages. Some sites may have surprisingly common names for their DIVs. A common custom filter which works everywhere may remove something annoying in one site, but it may break something useful in another.

it's almost always possible to create a unique filter.

for remove divs/spans/tables/scripts/forms
the keyword can be anything inside the element, not just the id or class name.

for CSS filters you can make them site specific like so:

Add javascript to all pages:
if(__amscript_cd(".site-domain.")){__amscript_wc('...css goes here...');};

with that being said actual site specific filters will be in v5.x when the new interface is added.
