Hi Igal,
All suggestions are welcome :)
Supporting this feature shouldn't be too difficult in theory because it is already working with this kind of aggregation (month are built from days, years from months...). The main problem is scalability for stats which require uniqueness like number of users or number of edits *per page*. That's why yearly stats can actually be disabled on some big wikis. So it would be feasible but with edits limitations for the range (like 3-5 millions) and it would be very slow to load with lots of edits.

One way to handle the scalability problem is to use HyperLogLog counters. These are an approximate algorithm for which you can store daily counters, and then merge the counters to get weekly/monthly/etc, avoiding the cost of doing the calculation over something like an entire year just for the one stat.  Of course because these are approximate they may not be exactly what you are looking for, just an idea.

Hello. It's amazing, thank you very much!
Could I suggest one more feature, please? With it, the tool will be
perfect. I'm talking about aggregation. Any kind of historical statistics
for some day, month or year can be also shown as range of time. For
example, if we have month statistics, we could fill From field to be Jan
2008 and To field to be May 2011, and get the aggregated numbers for this
range. Is it possible?
Thank you very much again,
Igal (User:IKhitron)
