How do you manage that Archive widget?

I'm using Wordpress. I'm using Collapsible Archive widget. Pros and cons.

It's either too lengthy (show every single post) like how it looks like now or just a single link to all posts. No other options available as far as I know. I have 39posts now and still growing. My sidebar is bursting already.

Any recommendation anyone?

Take a look at my bursting left sidebar with every single post listed at www.mumsafari.com.
