Remember the Second Rule of Systems Design:
If it ain't broke, don't fix it
I have had my fill of 'change for the sake of change' from my managers over the years. We have something that works superbly (most of the time) and supports a thriving and vibrant community (see, all those hours spent in meetings with the marketing droids has enlarged my vocabulary).
And this brings us to the First Rule of Systems Design:
The New System has to work AT LEAST as well as the system it will replace.
Any new "improvement" has a high bar to reach.
Also, "If I must read a large block of code here, I really need to put a zoom of 25% or 50%...", I submit that it is high time you had your eyes checked and your glasses prescription updated. I only need a 5% increase in size.
