Why isnt working with "mono" files as logical/simple/intuitive as working with layer files?

First of all, how does spectralayers define “mono”?

The reason why I ask is because it seems like spectralayers has a completely different definition when it comes to “mono” sources or “mono” files and working with “mono” files is not as INTUITIVE as working with layer files in spectralayers.

When you select a layer and solo it and export then the file is exported as so. When you de-select a channel (because usually the audio layer automatically has both channels linked/selected) and choose to select either left or right and export then the stereo channel is still exported (even when you solo either left or right).

Why does spectralayers do this? It’s not INTUITIVE dealing with “mono” files within spectralayers. I expect that when you select a channel (just like the behavior of selecting a layer) that the right or left (depending on whichever you select) would solo and become completely “mono” when exporting, however it still behaves as a stereo file when you export. Even when you solo, the export still treats it as a stereo file.

To add

When you de-select a channel and select only a right or left channel and apply a selection shouldnt the selection only apply to that channel? Why does the selection apply to both channels (even when you clearly have one channel selected)? Wouldn’t it be logical for channels to be treated the same way as layers (where when you select one channel only that channel is applied to when applying a selection)?
