Maybe not a huge issue, but I'd like to have numbers I can set, maybe with an up and down arrow, for the charge limit. Instead of sliding the bar to "about" 90% or whatever number.
My fat old fingers have a hard time getting the slider to the right spot. I use TeslaFi to set the number I want most of the time since it supports up/down arrows or just typing in a number.
Unless you are trying enter an odd number, you can just tap to the left or right on the battery picture to set 50, 80, 90 or 100% - no need to drag the slider.
