The thing I find myself wishing for is the ability to link to a specific reply within a thread other than the one I'm posting in. You'd think that viewing the source code of a thread would reveal the trick to that - every reply to the first reply has a "TO 1" button, after all - but I haven't had any luck trying it.
Switch back to your first browser window. Paste it into the url portion for a regular link in your reply. You can view source for each page, and if you look hard enough, you can find how links are coded, if you forget. You can also right click on a link and choose properties to show the url.
I just picked post #55 on this thread at random because it had a lot of posts
I hope that is what you meant. It takes too much time to get too fancy, but it is really handy to at least learn how to code links and also give them a description of your own.
