Same goes for compression settings.
I have to select the desired algo, and tick the checkboxes for each and every one of the new root folders (if I'm compressing one folder, closing the app, then compressing an another folder through the context menu).
Yes, you can "apply to all" if you're doing a batch, but, playing a guessing game as to whether I selected the right algo or not before I started the compression process on a beefy folder - is ... not fun at all.
Again, v3.8 saved those settings, so when you opened up the app again - the desired algo was already selected (and "secondary" options were saved in the app's settings, ofc).
