I am seriously thinking about adding FlagCounter on my revised blog (yet to be posted).  I have some suggestions,

1) Flag counter seems to need an "Omit Host" option; as in the person(s) who the site belongs to.
2) Data Presentation Option: Image, Country Abbr., Total Visitors, Return Visitors, Unique Visitors (one time visitors)
3) Option for both Host, or VISITOR to set the time period (Today From Midnight, Last 24 hours, Last 7 days, Last 30 Days, Last 365 Days, Calendar Last Week, Calendar Last Month, Calendar Last Year. Total History of Site, or possibly even more dynamically a User defined period of time) of the information presented.
4) Report generation (Day by day, Month by Month; Year by Year). For online or offline.

As I am not using this directly/yet maybe there are ways of doing these things already that are not apparent to me at this time. Please excuse this post if there are.  Note: There is a record keeping difference between last 'x' period of time vs. actual calendar unit.
