It adds some more advanced functionality like buttons to delete/report posts without having to go to the bottom of the page. With the current version it is also possible to `hide’ threads, a feature from the 4chan extension for Firefox that is sorely missed by Opera users.

Download: 4chan.js, 02/06/09

Has to be placed into your Opera UserJS directory, which can be set up under Preferences > Advanced > Content > JavaScript Options.

Full list of features

• Kills any iframes (you know who you are)
• Also kills any <embed> tags to prevent, for example, background sound caused by Flash objects.
• `Fixes’ quoting, that is, the comment box now properly advances to a new line after clicking on a post id. Also note that you can CTRL-click post ids to prevent the window from jumping up to the comment box.
• Adds buttons to delete, report and hide posts/threads.
• Also adds noko and sage boxes next to the e-Mail text control.

Notes on compatibility with fychan.js

The buttons to delete, report and hide posts do not work with fychan. Might or might not work on a fix for this in the future.
