I have been having this rather annoying issue for about 5 years now (probably longer - can't remember 😉 ) I use mouse wheel to navigate the options within Export Settings, but you are setting the focus on wherever the cursor is located - this results in, for example, ending up with changing Channels to 5.1 from Stereo rather than scrolling to the Bitrate where I want to get to. This is a bad UX... Please fix this! (Applies to all Mac OS (at least) and all AME versions from the beginning AFAIA.)
Have something to add?
