Uninstall

if I uninstall the plugin, how does it affect the contents?
There’ s no problems with the plugin itself – working just fine. I’ve decided to simply not use tabs, which for future is not an issue but can they be removed from existing contents without affecting/losing anything – text/images/videos?
