I would give it the ability to auto check if the comment has been listed, and then place into seperate project files, the ones that HAVE been listed, the ones that definately failed (404 etc) and the ones that went through but couldn't be found.
This way, when you select the autocheck feature a week or so later, it can run the check again, and just auto-amend the text files (or possibly .csv) that you were working on.
Also, better success rate when checking shared proxies as it seems to have a high fail rate on this and a lot of "shared proxy" providers tell people not to use SB to run a check on the proxies they provide because of this.
