The mouse cursor is a bit like a guest that refuses to leave the
party.

You use it to find a spot on the page, then you want  to start typing,
and you pay attention to the caret cursor. The mouse cursor at this
point is irrelevant. But the ruddy thing is often sitting right on top
of what you want to type obscuring your view.

I think mice should learn to behave more politely. They should quietly
fade away whenever you are actively typing and then come back, or
should scoot out the way of what you are typing.

A similar problem is the search. When the text I want is found, it
might be only a few letters. there need to be some fast and standard
way to help my eye see it.  I can often stare and stare and can't tell
if either nothing was found, so the find was hidden in a sea of
characters.
