Grouping, tagging, etc suggestions?

File search / comparison / similarity / find / etc. <- been thinking could this have some kind of auto grouping / tagging suggestions? Perhaps mostly grouping.

When one finds a bunch of images among much of images grouping, renaming, moving, etc isn’t so handy as one could think.

Perhaps if there would be select-tag along with selection (on files on the GUI) then one could freely click here and there along other images: but loosing the selection of a file isn’t actually a loss if you’ve chosen to tick a selection tag to those images that were good to go~
