You've been successful then, haven't you? Balance control and a "mono switch" (even if a little inconvenient) are both available through the WiiM Home App. And yes, I consider them useful, too.Mono/ balance....
From the very beginning of Wiim, I insisted on this pair of functions, who associate, which are very useful for adjusting things correctly and easily...
Not sure if that was understood correctly...
these functions having often disappeared from our integrated preamps, etc., for decades
Thank to wiim...

What is not available is a left/right time delay. This should not and cannot be integrated into a balance slider. If there's just a difference in level between both channels (e.g. due to a questionable mix) only the level should be corrected. Adding delay in case there's a different distance to both speakers from the listening position is a different topic, but also a niche application. Even adding delay won't restore perfect symmetry.
