I installed Mathematica Version 12.1 and there is a huge change in its look. All the notebooks and palettes are HUGE. And yet if I adjust them to 75% or 50% magnification some of the important text becomes too small to read. The entire appearance that I carefully designed with style sheets and that has worked for many previous versions has been destroyed.
I believe that a magnification of 100% should be the standard and should work for most people.
Is there some simple option that can be fixed to restore the previous appearance?
If it's a deliberate change made by Wolfram, what right is there to do that?
Also I still have V12.0 on my computer, but I can't open any notebooks with it.
