DK feature suggestion revisited: group by file name

[NeiNei]

Hi there,

on the this screencast https://www.youtube.com/watch?v=fJ6g6PO9WTc there 
is a patched DK version show which offers an additional grouping option: 
"group by filenames". As far as I understand it is related to 
https://bugs.kde.org/show_bug.cgi?id=318357 and
https://plus.google.com/+SebastianBerthold/posts/2RNd1c9YksN . In the 
context of this feature suggestion, there is a "geek feature" mentioned, 
grouping by regex rules. This seems to be somehow over the top with 
regards to user friendliness. As an alternative to that a much more 
easier user interface in the way the batch tool manager rename function 
works was suggested to overcome the regex hurdles.

However, I would like to ask the DK devs whether there are plans to add 
(part of) the functionality of the suggested group by filname feature in 
DK 5.4 or 5.5?

Thanks in advance,
NeiNei
