If you're using the Firefox version, you're on the older v1. However, if you're using the Chrome(uim) version, you're on v2, which is the updated and improved version. I recommend giving v2 a try, as it has addressed all the issues you mentioned. The icon behavior has been fixed, and there have been several other improvements, including better grouping and toolbar button resizing options. Let me know what you think!
