I often find that I will use the same command multiple times when performing a specific task.
Example: Center several table columns.
But this is not a task that I do every day, so pinning would be a greater annoyance than benefit.
Setting a hotkey for the command would perhaps work, but there are limited unique key combinations, and I would certainly have to look up the keypress as a reminder each session.
Seeing my most recent 10 commands would mean that repeat actions were easily accessible, and always up to date with the task at hand.
Other software, such as the DAW Reaper, use exactly this method.
