what used to be white space is now something interesting, great job!
I don't know how anyone can use Twitter without this script -- it's insanely useful. The replies pop up in the sidebar, sorted chronologically with the most recent at the top, very readable. This is one of the first greasemonkey scripts I install on every browser I use.
Works perfect, i can't find any thing to criticize.
It fits good in the right sidebar, so it does not bother you in any way.
Thanks for offering this script.
