I'd like to suggest that abp allow the inclusion of a default patterns.ini (which I believe can include both strict patterns and subscription URLs), which will be installed in a user's profile if they don't already have a patterns.ini. This will allow abp to to repackaged with an initial subscription appropriate for deploying to large numbers of users (e.g. Easylist, Easyprivacy, etc.). Currently, it's possible to specify a centrally managed patterns.ini, but write access to it must be controlled and individual users are not able to save changes (new filters, subscription updates, etc.). A default patterns.ini would allow deployment that automatically adds a subscription at first-run, but still allows users full control over their subscriptions and filters from that point forward.
