Suggest to use other color because the bbox color are in yellow already.

Suggest to use other color because the bbox color are in yellow already.

yes. agree with this.

For me,

• And the thickness can be reduced as well. For image with lots of annotation, can look messy.
• Provide a way to toggle on and off the guiding lines. Like a button.

Looks good to me

I think the toggle button should be under the bounding box. So it will be close to the bounding box button. And want to keep the info at the end.
