I tend to create shorts most often using the thermal tool. If I could
declair a layer to be reserved for one net then most of my mistakes
would be easy to spot.

This thread started where the trace optimizer created the short, so any
interactive checker
wouldn't help there;
When a short is happening, and it is the "hard to debug" kind, two nets
with more than a few
parts have just touched. If you set up a pseudo-netlist checker to run
for every action taken,
but quickly, minimally, it might help. For instance, the checker program
that runs after every action
could look at whether more than 1/3 the nodes of the average net in the
design were just added
to this net... that could be done without going through the whole
netlist, just the local nodes
being worked on. It could be fast.
There is a line drawing mode, called auto-DRC that won't let you create
shorts, perhaps that is sufficent
for your desires, although you can still creat shorts when adding polygons,
arcs, vias and elements ;-)
