I added category select option to the image banner widget. Now you can easily display banners only for certain categories. While adding the banner to your sidebar or widget area, just select its category from the dropdown. After you save the widget it will display only on the category page you selected. It will appear both on category archive pages and posts pages with same category.
I also updated category text widget which displays content/html based on the category. Now you can also select All categories. So you won’t need normal text widget anymore. You can easily convert your widget to a category specific or general content anytime. You can download latest version of the category text widget here.
