Format categories in the right area within one "box"

Dear EasyBlog Team,
In your example you have a format of the categories in one "box", see easyblog-categories.png

I have already made some template overrides for a couple of your modules, but mod_easyblogcategories works a little bit different than the others. It is not looping within the template file but within the controller (helper.php). So I tried to override it via mvc override, but I got this error: Fatal error: Cannot redeclare class modEasyBlogCategoriesHelper in C:\xampp\htdocs\ifs_portal\wwwroot\modules\mod_easyblogcategories\helper.php on line 270.

On the screenshot (easyblog_tagcloud_vs_categories.JPG) you can see what my problem is. I need the categories in one frame like the tags, but it seems to be necessary to override your controller to accomplish that.

Can you help me with that issue?

Thanks in advance and best regards
