wings-1.0.2-1.12.2.jar

Use controls menu to change Wings "Fly" key binding from R to some other key (eg: F)
Restart Minecraft
"Fly" is again bound to default R key

Expected: "Fly" is bound to F per user selection.

Thanks for the report! I've identified the issue and will work on the fix.

Released 1.0.3 is now out.

Thank you. This mod is amazing, by the way. I really look forward to where you go with the features.
