I've found the 'MIDI Log Box' to be very useful, however it also seems to be very limited for no real reason, my suggestion to improve this would be as follows:
<1> Increase the number of lines to 128, the current 80 line limit is too small and gets reduced even further by line over-wrap.
<2> Add the ability to filter Tx or Rx packets only, this would be very useful and make the most of the available lines.
<3> It would help if the box could be sized by the user, again this would avoid over-wrap and make it far easier to read, it could return to its default size on reload.
Any changes in this area should have little or no impact on the rest of the package, and therefore be low risk.
