Yes, I admit it looks like a bit geeky, but it always does this way when
it comes to regexes...

I would rather not introduce any new syntax to regexes - regex patterns
are standardized, and it's difficult to find a description of how they
can be used. Adding extra staff will break the comparability and make
their usage more difficult.

But you are, of course, right about the necessity of simplifying of
regex usage... IMO the are two things, that could be done in this area:

     1. adding some 'menu-buttons' (the same like for tag insertion in
        advrename) for faster access to some regex goodies
     2. importing from online library of some cool advrename templates

What about it?

What mime type .msv is ?
