Andyrage......dear Andy....the main problem( for me personally) ...is the lack of a fine liner tool...the sharpest fine line at present appears to be the eraze tool.....I know that this can be worked around by going very large in the pictures original size...and then size reducing to finish,,,but that doesnt alter the fact...you cannot fine line with any of the tools..with the exception of the erazer........ other users must have found the same problem.......at present I find the pencil is the next best thing to the erazer.....Please ignore this note if the problem has already been addressed............but I thought it best to mention it.....hope you dont mind....Regards...Jack.
