I would write a php function that does three things.
(i) checks to see if the browser remote IP address is you, and if it
isn't, does nothing - that lets all of your other users off the hook.
(ii) adds any error and debugging messages to a big chunk of memory.
(iii) RIGHT at the end of you page, calls the function again to
*display* the buffer contents in a <div> that overlays everything.
An alternative is to create a debug notice area in some empty bit of
real estate.
