I remember a few discussions (on which I think we disagreed :) ) about 
trying to integrate CSS into the DOM tree some how, possibly applying 
the attributes directly to the branches. I think I've learned enough 
about CSS since then to see that it might not be practical; basically 
supporting your position about it not being a good idea. (Although I 
think you disagreed on the principle of modularity.) Beyond that, I 
don't really have any thoughts on CSS. :-/

On a separate but tangentially related subject, some time soon, I'm 
going to start piecing together a central activity tree which will house 
information about URLs loaded within a certain lifetime (say the last 
4-5 hours). Basically, it'll list URLs directly requested, the images 
and other media files requested as a result of parsing the page's HTML, 
content statuses, sizes, and types, and possibly window/tab 
relationships, and window/tab history. I still have a lot of thought to 
put into this, and I hope to actually write out a simple design document 
before I actually start coding it. The basic idea is the URL manager 
that I think I had Michael begin on years ago, but a bit better thought 
out than what I had described at the time... :-) I know it might be best 
to reuse code or complete what was already started, but I want to start 
from scratch on it.
