I would love to have search volume metrics pulled into the suggested keywords table. I would also like to be able to see more than 10 suggested keywords. I really like Surfer's Keyword Explorer chrome extension, which gives keyword metrics and multiple tabs of keywords if available. It is also nice that you can click on the keyword and it takes you to a google search with that keyword so you can check out that SERP quickly.

This being said, having the rest of the metics you have in your chrome extension is very helpful, so I use yours mostly, but I really miss this part of Surfer's tool.
