I think MP3TAG is great!!  
But I do miss one thing.

Not every file has the same capitalization in the tags and/or filenames.  
I want a function in this program which converts all Uppercase, or all lowercase to in-between. (Don't know the correct naming for this, but I mean every word beginning with a capital).

For Example  
MICHAEL JACKSON - THIS IS IT.mp3  
Tags  
Artist: MICHAEL JACKSON  
Title: THIS IS IT

Conversion (by tag)  
Artist: Michael Jackson  
Title: This Is It  
Then renaming by Tags:  
Michael Jackson - This Is It.mp3

Or example:  
strange singer - 12sing now.mp3

Conversion (by filename)  
Strange Singer - 12Sing Now.mp3

... specifically look at $caps(), $caps2(), $caps3() what they can do for you.

Yes, Eichenwurm, you have read the request better than me.

PSV\_Supporter should use the action "Case conversion" set to "Mixed Case".

Okay, will look at that. I think $caps() does what I want.

But it can only be used when conversing from Tag to File, or File to Tag, or can I use it in the fields to the left?
