Ikon change option on Android

I recently buy a device from an other producer, that’s compatible with eWelink, and it has the option to change the ikon displaid, it has a screen to do that as in the picture below.
It would be useful and easy to identify the device in a long list like mine if, for example, the SonoffMini would have an option like that.

The display feature is available for 1-channel switches for now, and will be expand to other device later.

You are righ and is greate!

I like to ask ask you to verify why if I select to display as outlet the ikon doesn’t change it remain as switch!
