Hi, the ImageCleaner widget is amazing and very useful. I’ve got just a small suggestion to improve it: why don’t add an option (and a button) that says “Delete the whole batch”?
The cleaning process would proceed way faster 
Thanks!
An additional useful feature would be to show the losses related to the shown pictures (e.g. above the plotted pic). This might help to realize after how many batches it’s time to stop deleting as one can see the losses declining batch by batch (I assume the speed of loss decline will slow down, but especially with large data sets it’s hard to decide when to stop deleting manually).
