I would like to have the option to have my history auto-cleared at a particular time of the day (e.g. at midnight). I don’t always remember to clear my history, and when I need to use it, I often find that it is unusable because it has accumulated too much history without having been cleared at some point in between.
(Kind of) related side note: It would also be great to have the ability to only clear older history and preserve the history from the last X # of hours/days/weeks etc.
