Lovelace Thermostat Card - increase handle size


#1

I am using the lovelace thermostat card for controlling my smart thermostat.
I am having some trouble to tap+drag the handle (the little circle that you can drag along the curved track) through iOS app.

I was wondering if there is a possibility to increase the size of the handle to solve this.
It would be nice if this is user-customizable somehow.
