I probably shouldn't have picked text editor as the example, it's really not about that.

It's also a major source of WFM (works for me) syndrome, where something in your custom stuff is unintentionally needed by the build.
I'd rather be building things than playing with my tools. If I really need something esoteric, I'll find another tool or write a Python script
Like @kstenerud, I tend to keep the default settings as I am happy to just learn the default to at least avoid things from breaking, when the next IT/infrastructure update happens at "the company", or maybe I have to use a clean machine to do some coding.
Instead, I spend some time to look how I can be more productive (keyboard shortcuts, etc), and then will just leave it at that. I've had both types of colleagues: customizing/non-customizing, both types have been high performing.
A lot of the effort people devote to customizing their tools doesn't seem to be about productivity or effectiveness in any measurable sense.
Anecdata: don't think I have any? My best tools for years were pencil and paper, and I usually get things done, very fast.
So it's horses for courses.
