I've heard the changes are being made to the reply system, but I haven't seen anything yet. Most of the time I find it unnecessary to quote the person that the person I am replying to was replying to. What I'd like to see is the ability to highlight with the mouse what I want to reply to, then hit the reply button and have only what I highlighted appear in quotes.

I've noticed that the editor has a larger window now.

One thing I'd like is for the Reply button to always show. I tried using the forums on my iPhone and accidentally -1'd someone trying to hit the reply button. :/

Ive done that a number of times, I mark the topic to I can + it when i am on my desktop

I'm noticing when I edit a post that it's adding break lines when the text hits the edge of the smaller window instead of looping to the next line.

I hope you do at least use the reply button, else the other person will probably miss the fact that you replied to them. :P

Also it sucks for other users if you remove quotes since others may have trouble following the thread.

I usually copy what I want to reply to, hit reply, and then paste over everything between the top and bottom quote tags. It's more of a minor annoyance than anything, but still something I think should be fixed.

If there is multiple quotations in a post you are replying to, brackets are now cascading in nice way.
It's easier to find brackets you want to delete.

It appears to add unnecessary line breaks, though, if you reply to a post containing links.

Yeah, editing is kinda messed up imho, it breaks the lines, not only the links.
