 ''There might be a trac already for this although I could not find it''

 It would be very handy to have expression based labels.  This is something
 that I really miss coming from MapInfo as I tend to make labels that
 contain information from more than one column eg PipeSize + \n + PipeType

 I know I can do this by adding a new column however that is limited to
 tables that I can edit.  A lot of our tables are in MapInfo Tab format for
 just displaying purposes and because we still use MapInfo and it would be
 nice to have something that doesn't require a save to shape and table edit
 first.   So the expression label feature should not need the table to be
 editable.

 It would be good if it supported all the operations that the field
 calculator does eg + * / - and multiline
