Point import format manager hasn't really changed a lot in the last 30 years... It would be awesome if point import would check a file for commas and quit asking if they are there or not... It should be an easy check. Also, add the option to skip the first X number of lines of the file... Everyone that has a clue has a header on their point file, that they have to delete in order to use. Which then orphans the file, it no longer has the header info to tell the fields apart...
Also, could it give an error message if a line can't be processed, instead of just dying? A blank line at the end of the file shouldn't crash your import!
