I tried to submit the plugin,
but it was rejected straight away on the basis that
Volumio already has such facility as premium plugin. […] the install of this one will break the already existing plugin.
Given that a previous CD Playback plugin exists (but not maintained), I expected this one to at least be considered and reviewed.
Anyway, I won’t pursue that further at this stage, because I also understand it might get political given it’s available as a premium feature. But, if anyone doesn’t have premium subscription and wants to try this one out installing manually, I’ll be happy to give support.
And if core devs want to give feedback on why it broke the already existing plugin, that feedback will also be welcomed.
