The use case sounds informative, but I’m concerned that this feature could cause confusion in a number of places. For example, we need to prevent switching back and forth for a short period of time, consider whether the switch is still valid after a profile rename, and whether switching when VPN is disabled should be enabled on VPN …
We need to discuss this. In fact, users want to use the switch for other things, so maybe opening up the script in LuCI would be a good option?
BTW, have you tried our App? For non-technical users, it might be better to use the App for quick switching.
