Finally, thank you.
But, your response was a HUGE disappointment. 
1-2. Lame excuse, not possible? You're the coder, you've the power to change it. Right? DetlevD is backing me on this that these are BUGS.
3. Ok.
4. In short: lame. So I should populate all my empty tag values (which are set that way when the FLAC file is encoded) if I ever want to use your software?! Sheesh, that's lame.
I'm really disappointed after waiting several months.. and because now I've to find me a new tagging software.. and not just because you won't implement the feature in the 4th list item.. it's the 1-2 list items, I thought that those would be a clear case.
Oh well, I think that I should say thanks anyways, so, thanks, and bye (I'll follow this thread for some time).
