Explore tabs (why not multiple rows of tabs?)

Hi.

Some of my reports are extensive and need a large number of tabs, which Explore shows in a single row. This means lots of compressed and truncated tabs that are mostly unreadable unless you hover over them or click on them (even if you use really small sized letters).

So the question is: why not allow multiple rows of tabs? It's not unheard of in the Internet, Zendesk :-) And I, for one, would find it really useful.

Thank you.
