Sometimes I would like to hold my battery charge without adding a charging slot.
E.g. today my battery is unlikely to have enough charge to supply the whole day's demand. But its not worth charging at say 20p to then use that charge during 21p slots - after round trip losses. Better to simply hold my battery and keep for more expensive slots.... using grid during both those 20p & 21p slots.
Perhaps in the same way it's very easy to toggle charge slots on/off the same could be done with hold?
Either from the same page or additional page.
e.g. If same page it might be a single button selection to signify if you're toggling charge or hold?
With colour box edge as now blue for charge
And (say) green for hold
If hold and charge are both toggled on then charge would of course take precedent
I hope I've explained!
