dedicated 4chan browser

I have come up with an idea for a web browser devoted specifically to lurking 4chan/other chans. Some ideas I had for it are:

*built in Overchan-like sidebar
*enhanced board navigation in general
*a few extensions for those who want them (not firefox compatible though)
*custom download manager which (optionally) could upload to other users (sort of like bittorrent)

These are only a few of my ideas of course, and other cool ideas are welcome. Basically, the purpose would be to have a custom browser for all the "power lurkers" that could also help with the bandwidth issue. I'm wondering, though, if people would actually be interested in using such a thing.

* enhanced board navigation in general
That's not an idea, that's at best a suggestion for what type of idea to come up with.

*a few extensions for those who want them (not firefox compatible though)
Same.

*custom download manager which (optionally) could upload to other users (sort of like bittorrent)
Such an extension exists.

*built in Overchan-like sidebar
Why? We have a sidebar


Also, enhanced borad navitagion already done, se 4chan extension.

I'm sorry, did I crush your idea? :(
