A request about the console

Is there a way to make the console update live?
I am missing some information because of a 'failure to write to log file':


(This log is only here to show a write error, and can mostly be ignored)

I end up missing vital information about another problem I am trying to solve because it's not being written to the log files...a live updated console (maybe limited to 100 lines or something) would be more convenient. maybe even a button to switch between live update (for debugging) and normal (for less drag).
