Horizontal Tabs (Page Builder Element in Kallyas WordPress theme v4.0 )

tabs are deceiving.. developers, why don't you add the text area withing the tab are, instead of us adding it manually? what if we have a sidebar and all that. and when you rezise that element of the tabs it re configures the whole page. and no way yo undo. yea why is there no undo tab? so i dont develop and waste time.. if an element doesn't work i have to redesign the whole page again and again. saving is not an option when you editing live.

Tabs are pretty straight forward, but opening with a link anchor element is a big problem. especially in my case where i am trying to open a tab located within another tab. things really gets complex. we need a tutorial for this.
