These two commands can be placed in your rootlogon.C file.
You can also disable these two options via the Canvas toolbar menu.

I agree.
You can try
Root > pl = new TPaveLabel(x0,y0,x1,y1,"label","brNDC")
The NDC (Normalized Device Coordinate) means that the specified
coordinates x0,y0,x1,y1 are given in the pad NDC system [0,1]
You are independent of the lin/log scale.
I have modified the graphics editor in the new version in such a way
that all TPave (or derived classes) objects are correctly drawn
in lin or log scales.

You can insert your includes in a ifndef directive.
The __CINT__ is recognized by the CINT interpreter.
#ifndef __CINT__
#include <TFile.h>
#endif
{
// macro
}

This should be better documented anyhow.
