Cancel data tab

If one (accidentaly)click data tab , huge table having focus, possible with nice order by clause, one can then take long coffe break. Cancel sql that is run by data tab open, should be possible.

And this is big pain even if there is default LIMIT 1000, probably due to order by.

To mention again button "show all" should on click change to "do not show all" and hence change all (100.000 default I think) to 1000 back again.
