In primary schools one does not learn about //  or /. thus the need for 
parentheses is subtle.  Using FullForm (or writing in Lisp) makes such
issues disappear.

I think that making /. and // same precedence would not be a bad idea.

The double (or triple) clicking on the operator is nice to know about,
but doesn't help for people who compose programs off-line.
