Battery Schedule instructions

Is there an explanation for the ‘ battery schedule’ on the new app. Can I ask the app provider this question? But I don’t know how to contact them. Can anyone help please

iSave My guess is that for each half-hour slot, if it's within one of the charge timers, it's marked as 'buy', else if it's covered by a discharge timer, it's marked 'sell', else it's marked 'use'.
Oh, and if pause mode is other than neither, then it marks paused slots as such.

if you touch a slot, it seems to allow you to designate it, but I definitely won't be trusting it to edit timers that way - who knows which one it will modify. (But I didn't trust the quick settings buttons either.)

It's thoroughly confused by my setup.

Is it possible to just remove the Battery Schedule paine?
And if disabled, does it stop the Axle control?

Not confused by the concept. I rather like the Buy/Sell/Use idea. It's on a rotating toggle so its easy to select one.
What throws me it's the time scale attached to it. I can't work out what the the start and end time is as the timeshown is in the middle of the segment! Surely a time marker should be aligned with the start, and end, of the segment?
