In the results table, you can tag each link that you are working on. If you have already contacted some webmasters for link removal, you can tag these as “mail sent” for example. This will help you keep track of all the webmasters that you contacted so far.
Also, you can add the tag “review” for all the links that you wish to review in detail. You can filter for a tag or even use a complex combination of tags. This feature makes it easier to keep track of what you have done with your links, e.g. mailed, removed, disavowed, reviewed, etc.
