Replacing suffixes and prefixes will cause too many problems as there may be a release called "TS Movie" so it'd be renamed incorrectly. This is really for the webmaster to do. I know some guy on these forums did it but I don't agree with the feature due to it's unreliability.
As for a "check all" link, everyone wants this but it defeats the point of webmasters paying to be ticked by default (as everyone will just tick all sites anyway). So the only way I could go about doing this without affecting silver/gold members would be to make it members only or something. I'll look into it soon though.
Also, I changed the link verification system so it's much more accurate now and does not require the drop-down box.
