The usability of the site grows if you use such thing as tabs. Tabs help to locate much more meaningful to the visitor information at the top. Now this can be done by inserting the code.

Therefore, I propose to include tabs in a set of standard tools of the programm. To be able to drag and drop the icon of "tabs" in the cell, quickly set the number and name of the tubs. Controls could be like in e-mail form.
