Adding any field in Tiddly Commander erases all main field content?

[Jake]

Yeah, I know, I read this: "Note: This will overwrite the existing fileds!" but I thought it would be the case only if the field I'm adding to the selected batch already exists in some of those tiddlers, but not the main text field!

So, my questions are: 

1. Why does that "awesome feature" exist?

2. Why it erases only the main text field then? All the other fields remain intact.

3. Why in the warning note it is not mentioned explicitly? "Your MAIN TEXT FIELD WILL BE DELETED". It is not "overwritten". I did not put another value into it and TC didn't place anything instead, it just deleted it. So - say that in a warning!

and the main one:

4. How to bypass that? How to add a new field to a batch of tiddlers WITHOUT erasing the WHOLE main content of those tiddlers?

I knew smth like that could happen, so backed up and no actual harm's done, but still that was quite a surprise...

It has to be a bug! I mentioned it twice already. I'm sure Mohammad will fix it once he realises the problem exists..
