Add STOP TIME to charging (not just start time) and add Charge Scheduling to Tesla app.

In the Model 3, you can currently set a START TIME for charging. It would be nice to be able to add a STOP TIME as well, to prevent your car from charging when electricity rates may be higher. Also build this charge scheduling feature into the app.

More details:

Being able to set a charge START time in the car is useful as it allows you to start charging your car during off-peak hours where you electricity rate may be lower. But for those who charge from a standard 120V plug at 3-4 miles/hour, a single 8-hour or 10-hour charging session may not be long enough to fully charge your car. Currently if you want your car to STOP charging, you have to remember to stop charging either in the car or in the Tesla app.

On more than one occasion, I've forgotten to manually stop charging, which led to my Model 3 charging all day during peak hours. <Insert sad face emoticon here>. Also, the current feature to set a start time for charging is only in the car's control screen, not in the Tesla app. 

The new feature I'm proposing is to enable real charge scheduling in both the car and in the Tesla app. It would be done with check-boxes and adjustable times via a scroll-type time adjustment. Example:

Scheduled Charging:

Day | Stop Charging | Start Charging

Sunday | all day

Monday | 10:00 AM | 10:00 PM

Tuesday | 10:00 AM | 10:00 PM

Wednesday | 10:00 AM | 10:00 PM

Thursday | 10:00 AM | 10:00 PM

Friday | 10:00 AM | 10:00 PM

Saturday | All Day

While waiting for Tesla to implement this, if you have an Android phone you can use the "Dashboard for Tesla" app (SG57 Productions) to do exactly this. I've used it with my Model X and it works very well. It is a paid app but I felt it was well worth the cost for the extra functionality it offered.

You can already set a charge percent limit.  Why not use that to extrapolate the stop time? If you estimate the battery will be, say, 70% charged by the time rates go up, then just set the charge limit to 70% and it'll stop charging before rates go up.

you can add scheduled leave time and charging will finish at that time, but not from the phone yet
