After I remove a handful of key points in the Keypoints Editor I get the following error: “Failed to save the edited keypoints for an unknown reason!”
… I’ve tried restarting my PC and all, but nothing… any guidance would be helpful.

We haven’t tested this feature out in years. Um, it’s been basically un-maintained. Keypoints have not been a feature folks have been using of the camera.
Ibrahim is on a fishing trip right now but can debug when he gets back.

Rodger that, I appreciate it!
that being said, what I’m trying to do is track a small feature change, a small rectangular actuation feature going from verticle (lets say 90 degrees) to a 60 degree state.
if keypoints isn’t the way to track that, how would you recommend I go about that? I’d like to say have a green LED on when it’s in the 90* state and red when it’s in the 60* state.
Let me know your thoughts 
If you’d like to share code I’ve provided a folder for you to be able to put samples in

Hi, everyone is asking for free code from us these days. We can no longer do this. Just provide pointers.
Um, I’d use the find_line segments method and filter the line segments returned and then track the appropriate one.
Hi, I just tried the keypoints editor and it seems to be working fine. Are you editing a descriptor saved on the flash FS on the camera ? Note the editor creates backups of the descriptor+image before saving, you may run out of space if you’re using the internal flash filesystem. Try copying the descriptor+image to PC first then edit.
