We can do that now (and have to in the case of the lost output) but would much rather it all stay in the output bar.
Perhaps, if the buffer size is going to be increased, maybe there could be a buffer dump to file in the current directory if the threshold is reached. A bonus option would be to have the buffer size editable and/or the dump an on/off option (which would be necessary if it had any effect on performance).
Thanks!
