To change the interface, the extension will need to modify lots of the DOM and/or styles, while I'm not a style magician if enough people show interest in getting an extension that changes the theme of the forum I'll work it out somehow.

altcoins and bounty programs are a bit different since it'll include loading threads and checking them, which can increase the load time of page, I can however give you an option to create your own 'sticky links' to threads.

I have the feeling you're confusing things here, I'm not associated with the forum managers, I'm doing this just to try giving something to the community.
