[Plugin: Collapsing Archives] Help! Fix For Only Current Year?

I absolutely LOVE this plugin. However, my archives page is currently set up so that it only displays the months available for the current year, and I can’t seem to get that same limit with this plugin. I’d love to use the expanding archives, but I’d like to only display the current year’s worth of posts. Can anyone help me with a fix for this?

Thanks in advance.
