Some widget has caching enabled. So new contents won't updated right away. You can disable caching to have it load new contents everytime.
xfrocks @Blast If you put it in a sidebar position, it will delete the existing sidebar. If you put it in a hook position, it will remove all existing contents of that hook.
Kinda foreign to me. Below the Avatar/Personal Info is the Clear Contents, I can't seem to control/find the Personal Info widget.
If you have widgets in the same position as the Clear Contents widget, it will remove any widgets that have lower display order. Regarding the tabs, you can set it with CSS. But normally it's best to let it resize automatically.
