One more tip, Users here often don't get immediately that labeling with toolbar require to put layer in editing mode. Maybe could we append a comment in data defined options : [..] Define attribute fields and activate editing of layer to enable labeling map tools. [..]

I couldn't find a way to enable the move / rotate tools in toolbar, in edit mode, after having defined fields for X and Y in expression. Tools that opens a dialog to modify font, text.. is working, but I couldn't change Y X values in it. Is this an issue or a I missing something? There is a short description about this below those settings: "( Define attribute fields to enable labeling map tools )" It means that only an attribute field mapping data definition can be used to enable the labeling map tools (e.g. Move, Rotate, Change Properties). An expression does not work. Since those tools directly edit the attribute table, access to the field needs to be established, i.e. a data defined mapped attribute field. While it is possible to find out what attribute fields (aka columns) are referenced within an expression, there is no simple means of determining any one of those fields are intended to be open for writing new values. It is possible when there is only one field in the expression, and no other parts to the expression, to use it directly, but then why not just map a field? There are use cases for allowing expressions for all of those settings (X, Y, Alignments, Rotation), so limiting those data definitions to only allowing attribute field mappings would not be a good idea. It looks like the 1 line help description, noted above, needs more work. Maybe invert the logic?: "(Defining expressions will disable labeling map tools)" Also, a good and concise contextual help needs drafted to explain new labeling options and how they work. Then, expanded upon for inclusion in general documentation.
