I'm having trouble reproducing the crash when saving the settings file. I'm not running as administrator so it could be related to that. When the AWS credentials are fixed I'll try running the built artifact as administrator to see if I can replicate the problem.
Focus settings are loading. See my UX notes below.
Remaining issues:
I just realized that "Synth" is "Synthetic" as applied to the user settings file name. I recommend spelling out the full word instead of using the abbreviation. Maybe I'm special, but it had me confused.
When I click "Clear All" it deletes my files. Perhaps that is intended, but as a naive user of this feature I was surprised that it deleted my saved files and kept loading the default "SynthEightDefaultSettings" thinking it was my user saved settings (and then wondering why my settings didn't load). Perhaps renaming this button "Delete Saved Settings" or something similar might make it more clear. The best solution might just be to remove the button since the user can delete settings files using the file browser.
Sometimes when I load or save settings files the file selection window appears minimized. This may be because I'm not running as administrator and I'll re-test as described above.
CI/CD not configured properly for AWS credentials. Will fix. Good thing to find out in this tiny PR.
