It took me a sec, but I figured out what he means. He's turning off the
pins/pads so that they're not in the way while he's routing on inner
layers.
The problem is that when you turn off the pins/pads, it turns them off for
all layers. On the inner layers a plated thru-hole will (often) have a
circuilar pad around it, not to mention that there is actually a hole
through the board. With pins/pads off, there is no indication of this this
at all and you can route a trace straight through a through-hole with out
realizing it (or on the top or bottom layer too, actually).
Hence the feature's he's asking for. If you could turn off surface mount
pads without turning off pins, then this wouldn't be a problem. Or, if we
had an "online-DRC" that would prevent you from drawing things that
violated design rules, it would also prevent you from doing this.
The quickest fix for this, I think, is to change things slightly so that
pins and vias are grouped together for visibility and pads are their own
separate "layer". The right way to do this probably involves reworking the
layer system, but this is a pretty quick hack that should work for now.
I opened a bug report on LaunchPad:
