In "Backlinks" tab there is an option to add a filter, e.g. view just the backlinks with anchor "ABC" or from pages with title "QWE".
It would be very useful to have an option to apply more than one such filter at a time, e.g. backlinks without anchor "ABC" AND without anchor "QWE", and so forth.
Thanks to this, it'd be easier to track the effects of different SEO campaigns or see what percentage of total backlinks comes from a specific "share this page" mechanism.
