RFE: Search Webmin Actions Log "Since"

When searching the Webmin Actions Log, I often want to display the last several days, in other words everything "since" a certain day. In order to do this, I currently have to use the "Between" option, which works fine, but it requires the current date to be filled in on the right side. It would be much easier if it always assumed the current date if the right side is blank, or if there were a separate "since" option that doesn't require the current to be entered. Alternatively, there could be an option to display the "last X days", which would just require entering a number instead of a date at all.
