Show all

I would suggest that in data tab, data grid background would be different colored (perhaps a variant of gray)
while 'show all' button is enabled.

That is, while not all records are in grid(limited by default limitation)

Was just CTRL+F and nothing there doh setting filter showed thing, and again CTRL+F .... (-:

Or mybe show all button text colored red, while enabled.
Doh I would see that as ugly.
