Settings for daily and weekly reports

Dear Devs,

Your plugin has great functionality but settings are pure wizardry. Once we’re thinking we got them cracked something weird happens to reports, they stop sending or send weird data from weird timespans, therefore I’m writing for a official settings for two simple use cases:

1. daily reporting – on each day X send a report containing stats for a day X-1 plus a table showing previous 7 days (X-1 to X-7)
2. weekly reporting – send a report on Monday containing cumulative stats for the past week (Mon to Sun) + a tabel for the past seven days (Mon – Sun).

Screenshots will be greatly appreciated.

Many thanks in advance!
