Hackernews Userscript by Drake Rossman

The extension provides features, which allow users to filter submissions based on a text or a regular expression:
- Filter submissions by text in title or link
- Filter comments by text
- Hide submissions and comments from a specific user
- Get visual feedback on how many items were hidden by a particular filter
- Toggle hide of all the children for a hidden parent comment
- Show [hidden] placeholder in place of hidden items
- Hide an individual submission, without auto-loading the next one. You can hide everything on the page, and it will stay blank!
