Everything could be possible I guess. It just depends what you want to achieve. Is it just to have a (monthly) overview? I think something like that could be probably useful for the "Statistics" area.

If the purpose is to find a transaction during a timeperiod in the past, a filter in the "Overview" area could be very useful. Maybe even one that also finds results by "EOS Address" or "Reference text"

Thanks a lot for your feedback. Inspired me!
