It's just a small thing. But it always confuses me that toggle switches in REI3 are ON/1 on the left and OFF/0 on the right. Other platforms that people are familiar with (like Android, iOS, macOS) use toggle switches the other way round.
Therefore, I would like to suggest to either mirror switches in REI3 in general, or have the option to customize it in that way. – Thanks for considering this!
