Nice sleek GUI, but reports too many false positives for broken links. Should be restricted to 404 responses only, or at least provide it as an option. The deduplicator function works, but the GUI provides no way to group-select detected items. Users with perhaps fifty or more duplicate URLs should expect to click "delete" for an unreasonable amount of time. I had over 400, so it was unfortunately an instant uninstall for me. If the developer fleshes out the options a LITTLE more, I may be back.
