new to Moode, just checked a few things

[foormea]

Hi!

I just bought a RPI Pi Zero W and a HiFiBerry DAC+ Zero.

I first tried HiFiBerryOS, but it didn't work well with the equalizer. So I tried something else.
I then tried Volumio. It had what I wanted (equalizer, Spotify sink, bluetooth sink). Except you need to pay for the bluetooth sink.

So I'm trying Moode I quite like it, especially that it's based on Buster.

So far it seems to do more or less what I want. I've just tried Bluetooth, it works, and Spotify works (Spotify's "initial volume" in settings got me a bit confused at first).
Anyway, it seems like Moode has difficulties letting go of Bluetooth devices? If I'm playing something over Bluetooth, and restart Spotify over WiFi, then it seems every so often the volume will go up/down as the Bluetooth device shows signs of life. Is that expected? Am I expected to manually go into the UI to unpair the Bluetooth device?
How can I unpair the Bluetooth device if Moode's UI becomes impossible to access if Spotify is playing?
Can I edit the equalizer without spotting Spotify?

Thank you.
