Hi Dopus Team.
As always, thank you for the best and most useful piece of software since '90
I was doing a nested regex batch rename of 4K+ files and realized there is no option to hide the 95% percent of the files that wouldn't be affected by the rename in the preview window. Not super easy when checking the regex doesn't accidentally screw up something.
Would be neat to have in the 'Rename Dialog' an extra tick box in the options section with 'show affected files only' (or 'hide unaffected files") as you want 
Thank you !
There was some discussion of it in this thread:
