This is a pre production unit. There may be changes. If there was, I would prefer a non recessed cross feed switch. That's it. I would actually prefer and like it that the gain was recessed. If there was a way to change it without a pen while still not being a problem of sliding the band. I would go for it, but as of this moment, there is no other way.
Of course there is other ways they could do it. They could have a switch that is less recessed then the current implementation, making the switch strong would easily prevent it from changing by accident in your pocket. They could always have an option to lock it from switching.
Not a huge deal really, just nitpicking, but it could be done better
