Let a tap look instant and keep the spinner for a command that really takes a while (0.2.70)

Home Assistant answered every command in 342-599 ms on a real installation,
yet a tile was busy for at least a second and up to six without a confirming
state. Now nothing is drawn for the first 400 ms, a tap that switches shows
the new stand at once as Home Assistant's own switch does, and the sheet
appears only for a slow command. Home Assistant's "it worked" answer ends the
wait 800 ms later, which covers a stop on a cover that already stands still,
and a wait without any answer ends after three seconds instead of six. The
cards' keys, sliders, chips and the -/+ edit now ask for an answer too, so a
refusal shows wherever a finger presses.

Firmware 0.2.59. A 200 ms LVGL timer runs only while a command is under way.
