Hey, awesome extension!!!!
One feature i would really like to see is the ability to Lock a window so that no other links can be added/opened in the window similar to how the Sidewise window is locked.
For example i have window setup and titled "Work" where i keep all project related tabs that i usually always need opened. However throughout the day i will open other links from emails, etc.. and depending on which window is active at the time those links will open in my "Work" window and pollute it :) so i have to go through periodically and clean it up.
If i could lock the window then i wouldn't have to worry about this. Same feature would really come in handy for things like Pandora, turntable.fm, etc.. windows
