There should be a way to adjust the HUD position beyond anchoring it to one of eight points. Admittedly, I didn't give this much though when designing the mod.

Possible fix: Keep the existing config settings, but add X- and Y-offsets that will be added to the anchor position. This will allow the position to be fine-tuned without affecting existing instances.

Forgot to close this issue, it's been fixed for a while.
