is there a list of features somewhere and are the two listed possible to be disabled? DSP-by-default is an anti-pattern for audio products and I don't want to install an app without seeing what it does...

Pretty much all I care about in an app is discovery (does it list related podcasts?), organization (does it keep my listening history), and playback ordering (does it support chronological | reverse chronological | custom playback ordering for episodes of the same podcast?).
