here's some recommendation based on how i code elisp.
• never type single paren. I always type them in pairs. And never
delete one of them.
• use tree navigation to move between code.
• to delete or move parts of expression, select the whole expression,
cut & copy to move.
so, when i code in lisp, there is never ever unmatched parenthesis.
this method beats paren-edit mode.
the detail of my editing and setup is here:

to select current unit of sexp, i press one key, which is bound to
extend-selection, which is defined in my ergoemacs mode. The code is
shown here:
