[extension]How to hook up into CampaignFilterOpenUnopen ?


New Member
Hi, we need to extend campaining filter open/unopen to open/cliked link/unopen, is it possible without modification of core code ? We want to create extension for that in order to keep compatability with updates.

One more question, is it possible to add html to main area of window , not footer, sidebar or top nav via extension? (Preferably after specific block, we want to add option to share campaining via social networks in addition to send them via email, need to add action buttons to trigger right under open/unopen campaining list in "advanced options")
