Hello,  
I know that the help file mentions that 'All operations are non-case sensitive' but is there a possibility to filter CASE-SENSITIVELY ? :

```
  ex.: to be able to find "Studio" and not "studio"

```

Thanks in advance, Sincerely, Bruno.

Yes:  
add a (?-i) in front of Studio  
e.g.

%title% MATCHES ._(?-i)Studio._

Should filter the capital studios, not the small ones 😉

%title% MATCHES (?-i)Studio

with **(?-i)** making sure case sensitivity is turned on

Replace _%title%_ with whatever tag you need.
