Is it still possible to have these features included?
See: Enhancements: Rename dialog
As for me, specifically I would like to have the rename panel stay open, so I can do various renames, without having to re-launch and again select the files.
Or is it already available and am I overlooking it?
For me, pending the revised rename dialog, it would already be a major enhancement if a a kind of [Stay Open]-option would be added. Frankly, when I plan to do many renames, then I use a 3rd party renamer.
