Bug report for version 1.0:

   Text file editor:
      The hot-keys for Cut (Shift+Del), Copy (Ctrl+Ins),
      Paste (Shift+Ins), and Clear (Ctrl+Del) commands
      available in the File|Edit menu do not seem to work
      sometimes.  An alternate set of conventional Ctrl+K
      binding hot-keys is always available for these commands.

           Command            Hot-key
           File|Edit|Paste    Ctrl+K, C
           File|Edit|Copy     Ctrl+K, K
           File|Edit|Cut      Ctrl+K, Y

   Data display:
      The translate command in Data|Data Presentation window
      crashes the computer system sometimes.

   RAM memory exhausted:
      In addition to the description in the manaul, this bug
      can also appear even if there is enough memory for an
      operation.  In this case, MEGA is experiencing a conflict
      with some memory resident program.  Please try to remove
      these memory resident programs and check if MEGA runs.

Future enhancements:

   New tree-printing functions:
      Support for PostScript vector format outputs to printers
           and text files.
      PCX graphics output for editing in other graphics editors.
      Support for more printers.

      Choice line width for drawing.
      Choice of page margins.
      Choice of more fonts.

   Include support for the extended and expanded memories.
