Spotify feature request

It’s great that Spotify has an in app EQ, but I need to change the EQ depending on the device I’m listening with. That device may be headphones plugged directly into my phone, it may be the phones speaker, or it may be a Bluetooth device. Unfortunately not only does Spotify not allow me to save settings on a per device level, but once a Bluetooth device is connected, the EQ and volume level settings cannot be changed (on iOS) Oh also... the repeat button. Why would you move it!!!???
