Love the new version. I currently have my forum index categories all set to collapse by default except the first three. There seems to be a small problem with this though, as my users are complaining about their settings not being saved between browser sessions. For example, some users are collapsing those categories and expanding the ones they normally use. These settings will stay intact when they return to the forum index, but if they close out the browser and open it again, their settings are reset. I tried this for myself in Chrome without deleting my cookies before closing the browser, and got the same result.
