Thanks for the nice app and Apple Watch support!
For the glance, I agree with ruby110 that it would be even more useful to indicate if the car is attached to power. The car silhouette glance you have currently displayed could be replaced by a new one with a trailing power cord when plugged in...
Yup, my plan for version 2.0 is to have graphics for all scenarios whether in glance or any other place where the car is shown: Locked or unlocked, HVAC on or off, rear and front defrosters on or off, charge port open or closed, car plugged in or not, roof open or not, trunk or frunk open or not, each of the four doors open or not.
It's just a lot of graphics to create, so I didn't make all of them for version 1.0 for the sake of getting this app out there sooner rather than later.
