For Amazon's Mechanical Turk (mturk.com). Adds ability to mark HIT groups ignored. Saves group ids you ignore in localstorage.
This extension adds a link 'ignore' to the right side of a group (just after the link "View a HIT in this group." Clicking the ignore link will mark a group as ignored which is visually represented by 'greying out' the group.
This is useful if you are seeing the same group appear while browsing for HITs and want to mark them as groups you are not interested in.
Note that even while ignored a group is still fully functional on the site. It is only altered visually.
