Request: Limit the timeframe that the log is kept

Hi, I think the title says it all.

It would be great to be able to limit the log’s timeframe, so the amount of data doesn’t get too big on sites with a lot of activity.

I’ve been having timeout issues while trying to delete more than 300 activities at once, so keeping it in check manually has been a bit frustrating. (I’ve had more than a few thousand entries)

I’m looking forward to hear what you think.
