How to make 'Recent Comments' the default tab
I'm sorry but I didn't follow you. What do you mean saying the Default Widget? If you want to use your theme widget you can use it separately. wpDiscuz Widgets addon also has a Recent Comments widget, you can use it in tabs of addon widgets. You can't put theme widgets in wpDiscuz Widgets addon Tabs. This is something impossible. The source of these data and HTML code are located in different places.
It like to second this. I'd like the option to reorder the tabs, setting one as default on top. Right now the order is Most upvoted (top)/Active threads/Most comments/Most acive commenter/Latest comments.
I'd like to have latest comments on top. Right now I just disable the others (including most active, because it just shows the bloggers themselves are active...)
