Automates the tedious task of visiting other peoples' okcupid profiles.

Duplicate OKC's think you both like' these words 'feature'. Includes option to define your own custom word search.

Appends to the title of the page with the mail subject line or journal post heading (if you go to the permalink). This way you can bookmark things effortlessly, go through your Firefox history with the AwesomeBar, etc.

On OkCupid profiles' tests pages, assume you are more interested in results to tests you have taken too, and thus show them on top.

Lets you split personality award badges into three groups (as perceived by you): the positive, neutral and negative traits. Badges on profiles you visit will then be grouped accordingly.

Prevent the User Tests section in the sidebar of the OkCupid root page from making the content below jump around, as it cycles through different-height entries, nor pan to the top of the document when clicking pause / unpause.

Shows poster name and post title in OkCupid's stupid "this post" journal links.

Links the Compare page from the personality awards section on the profile page, and makes it actually readable:
