[Daa98]

Thank for your work! It's very useful for me!

It can be done, if a lot of people want this feature, I can add it. Please react to original post to indicate interest. Feel free to work on this feature too, I'll accept a pull request that adds this functionality.

Suggested workaround: I would recommend uploading the dataset to CVAT (it should be super easy to do that), and using that for label verification (and deleting).

I'll be adding this feature tonight.
