Just a couple of suggestions...

Can you make a "Quick Reply" link text based? It is annoying when you want to quick reply, but have to wait for the whole page to load and the final thing to load is the "Quick Reply" picture...

So a text base "Quick Post" link right beside the reply, edit, quote links... i think is necessary...

And also... can you make it so that when you quick reply you get redirected to the last post instead of the first page?

I think that's all... nothing critial... just something i though can make things flow better...
