Thank you for the great effort, you are putting into this project :) There is, however, a feature I miss; rotated bounding boxes. Especially when objects are thin and diagonal, an ordinary bounding box fits poorly. Examples of such cases are shown here: rotated bounding boxes

A way annotation could be

if I'm in page 2 and once I delete the images that don't have a person it brings me back to page one

when a user creates a label (e.g. not in image) of an object, they should be warned if they are creating a label which contradicts an existing one with the option to delete one of them (given they are permitted to) or to lower the validation of the existing label.
