I just wish to have this excellent feature for Pro Sites plugin.
Currently we can only see the stats from Pro Sites menu. It will be cool and more useful for data interpretation works if we can just download that in the format of PDF/Excel either weekly,monthly or yearly.
Also with current stats, we are not able to get the sites name that got registered during particular time. Just think if we can get the list of blogs that signed up on 7/02/2015 how cool is that? With this data we could easily add little fields in excel sheets to manage its accounts,activity etc
Please share your thoughts.
