Hi, about the possibility to add observation labels (or "markers"?) some practical issues. - why no "help" button in the dialog ("add some from file now?"), in analogy to the help button that you get for adding series labels? - IMHO it would be good to have a facility to type them manually in gretl. Often it's just 10 or 20 or so countries or regions or whatever. Right now I had to create this text file with the labels just to satisfy gretl. thanks, sven
