I was curious if anyone could help me achieve this. I have a lot of different catagories, which I use quite a bit. But the list is so long that I would prefer it just show, say the most recent 4 or 5 used catagories and then have the rest in collapabe form.
In such a way that would work simlilar to the "Read More" option in the entry.

Also, I remember seeing a plug-in to bundle Archives in the sidebar that are for previous years into just 2004 Archives, 2003 Archives... and so on. Now I can't seem to find that.

I am using the most recent version of MT.
