Tell me where is the untagged region

[weida wang]

Bug Report : Hi，the feature of using trained model to auto predict is very useful, but i find some trouble during using it, that is i can't find where is the untagged region and it prompt message as below screenshot shows, maybe it is too small, or maybe its gray color is close to image, moreover the region is generated by model, thus i totally have no idea where it is ! So i want the VOTT to tell me ~

Question : what other kind of custom model it support, e.g. YOLO ?
Feature Request : Could we have the features of open in the folder and rename and remove awaywhen right click the image.
Below screenshot shows after i deleted this image, so i want to remove is away from this assets.
