As I have a second monitor, I have VoiceAttack visible at all times, which allows me to keep an eye on the log to see whether my speech commands are recognized; With shortcut commands(I.E. keypresses, joystick buttons, and mouse), the log tends to scroll quickly, and the movement in the corner of my eye is quite distracting.
Therefore, I propose:
Either a "Hide shortcut commands", where those commands are still logged, but not shown(allowing you to toggle the option off and see what was triggered before if you need to).
Or, if the former is technically difficult(as the "log" appears to only be kept by the list itself, as toggling "Show latest entry only" deletes everything else), simply an "Exclude shortcut commands" option.
Ideally, while more complex to implement though much more flexible, a keyword based exclude; E.G. "Shortcut*;Listening*;Unrecognized*;*Pause for [0..3] seconds*", perhaps with a toggle option from the log context menu(E.G. "Use custom exclude list").
EDIT: While it requires modifying all affected commands, I now use the "Ignore an Unrecognized Word or Phrase" action to hide the log entry.
