Just catching up
Planner columns - now start on Monday in 28 day view (were already starting from Monday in 7 and 14 day view).
Planner totals - are already there just below the day and date. If you select "Show > Done jobs" from the dropdown top right it will also include done work.
Mobile app totals - coming in the next (imminent) update to the mobile app along with expenses tab and various other tweaks and improvements. Update will come via the app store when approved.
Weekly turnover - you can find this under the "Accounts" tab where you can also see daily and monthly turnover (charged or collected) and filter by payment method and user.
BTW - there's a forum built right into Cleaner Planner now (tab top right next to "Settings") that might be a more appropriate place to ask CP specific questions and suggest features:
