Thanks. I like having the label flags. However the recommendation is to place the labels at the beginning of equations, anybody knows why? The problem is that the label flag then hides part of the equation.

Yes, I see the warning.

Another question. When I rename a label, references to it are automatically updated?

No.

I think not. Is there a way to rename a label and also have all references to it automatically updated?

I am not aware of such functionality, but it would definitely be very convenient. :-)

As a possible mitigation to this, try to use the replace functionality, perhaps it can search & replace also within labels and references... (I am not sure and I have no way ro try now).

A sidenote: there is a way to turn on showing labels as blue flags with the label names displayed. That way one has at least an overview of what the labels are, which is convenient if a document contains many of them. Also note that tab completion works on referencing labels within \ref, so you can cycle through the labels within the document even if you don't remember them.

As far as I remember there is a warning (window with errors) displayed if you open a file which has duplicate labels - the warnings say that numbers assigned to equations were changed, which happens if a duplicate label is encountered in a file. From this I would assume that the reference then references the last occasion of a duplicate label but don’t take my word for it.

When I have multiple labels with the same id, and a reference pointing to this id, where does the reference actually point? Is this defined?

Coming from Lyx, I would at least expect a warning. In a large document it might be hard to realize that you are using the same label id more than once.

Copying and pasting a label won't change the label. That is sensible design decision given that label assignments are always done manually.
You should simply modify one of the two labels by hand, and check the references.
