This Better Tag Cloud used to work wonderfully! But recently, I noticed that some tags wouldn't show up even though it had 1 post associated to it. And in the better tag cloud widget, I had specified for tags with "1" or more posts to be displayed.
Also, now that I have more content / tags, I tried to add additional tag ids to the Exclude / Include list in both the widget and on the Settings page. The changes failed to get updated on the website from the widget and Settings page.
I am using WP 3.1.1, but I noticed this problem even when I was on 3.1.0. I hope there can be improvements to this otherwise excellent plugin.
