I'm enjoying the new keyword tool. Thanks Google.
However the activity timeout period is way too small IMO. On my machines the keyword tool redirects to the Adwords homepage about 70 seconds after a new keyword tool page is displayed. This makes it amazingly difficult to actually study the keywords that you are looking at.
On my machines even if I am scrolling the page, looking at words or thinking about new language options - bang! - I'm on the Adwords homepage again.
