Custom widgets in APM Planner

has anyone tackled this new feature? Able to figure it out? A bit over my head.
could there be users out there that have custom widgets they’d like to share?

I’m not sure many people have used that feature. It’s always been there. I created a slider control to change param RC_FEEL_RP between 30 to 80. I couldn’t export it though. it looks like it needs some fixes.
